Sheet metal punching and cutting

Blanking is the use of the die material and other materials or processes, workers (sequence) or a stamping process for waste separation. Blanking is shearing, blanking, piercing and blunt short, notching, cutting, cutting, cutting, cutting, incision of tongue, refurbishment and other separation processes in General.

Separated from the sheet metal parts or blanks out the desired shape and size of the punching method. Blanking is the use of cutting edge of stamping die for the contours of the sheet along a shear deformation and separation. Blanking in stamping production accounted for the largest proportion. During the process of blanking, except near the cutting contour lines outside the metal sheet plastic deformation in itself will not produce, so by plate blanking the part still is a flat shape.

Main Procedures

Blanking can be classified as shearing, blanking, piercing, cutting and cutting and cutting and so on. ① cut was large plates into the Strip. Secondly, blanking is along a closed separation line on the required parts from the sheets separated. ③ cutting edge is cut out drawing Flash. Was rushed out on a sheet of black punch hole, Groove and shutters, etc.

Application

Blanking in addition outside as preparation, used for direct processing of the gasket, bike sprocket, instrument gears, cams, fork, instrument panel, as well as on the motor, electrical connectors in silicon steel, integrated circuits and so on.

Distance

The top die cutting edge of blanking die staggered called clearance. Clearance on shear deformation and failure process, blanking the affect quality, die life. Of blanking clearance on performance, sheet metal thickness of plate, punch and die structure and other factors, generally unilateral clearance sheets thickness loss.

Blanking of upper surface obtained after the blanking by the fallen angle, the shear plane, and Burr of the fracture surface consists of 4 parts (Figure 1). Plastic deformation of shear surface is formed, smooth surface and perpendicular to the plane of the sheet. Fracture surface is breaking the formation of rough surfaces, not perpendicular to the plane of the sheet, show some inclination. General blanking of dimensional accuracy is less than level 5, surface roughness is about α 50~10 r.

Precision blanking methods can improve the quality of blanking the upper surface, all smooth and vertical shear. Fine Blanking die cutting edge near a pair of scissors is the essence of material in a Triaxial compressive stress state in the deformation zone, suppress the occurrence of rupture, isolation is implemented to deformation of the material. To increase pressure in the blanking of peripheral ring, as seen in Figure 2, a v-shaped blank film, die gap decrease or negative clearance (punch than die).

When the volume is low, or blanking small thickness of sheet metal workpiece, latex or polyurethane instead of blanking die of a cutting edge, with another cutting edge completes the job. This method is known as blanking or polyurethane rubber blanking.

 General knowledge on “Cold forged machinery parts” 

Mechinery parts, also known as mechanical and mechanical components are composed of individual parts of the machine can not spin, which is the basic unit of machinery.

Manufacture of Mechinery parts is the whole process of converting raw materials into finished products. In terms of the machine, including the production of raw materials, transport and storage, production preparation, blank manufacturing, processing and heat treatment of parts, assembly and commissioning of products, paints, packaging and so on. In the production process, the raw materials directly change (or blank) shape, size, position and performance, making it a finished or semi-finished products of the process, called a process, which is the main part of the production process. The process can be divided into casting, forging, stamping, welding, heat treatment, machining, assembly and other categories. Machinery manufacturing process generally refers to the sum of the parts assembly process machining processes and machines, other processes are called secondary processes such as inspection, cleaning, oil seals, packing, transport, storage, power supply, equipment maintenance. The cutting method to gradually change shape, size and surface quality of rough or semi-finished products, making the process carried out by qualified parts, called the machining process. In machinery manufacturing, machining process is the most important process.

Mechinery can be divided into the following categories:

1, parts for connection. Such as threaded connection, wedge connection, pin coupling, coupling, splined, interference fit connection, elastic ring connection, riveting, welding and bonding and so on.

2, motion and energy transfer belt drive, friction wheel drive, key drive, harmonic drive, gear, ropes and other mechanical drive and screw drive transmission, and drive shafts, couplings, clutches and brakes corresponding shaft zero components.

 General knowledge on “The precision forging technology in the field of Auto parts manufacturing” 

Precision forging technology with high efficiency, low cost, low power, high quality, etc., in the automotive parts production is gaining more and more widely used. Based on deformation temperature metal forming different when, precision cold forging can be divided into cold forging, forming temperature, Asia hot forging, hot forging forming. Specifically:
1, cold forging forging generally at room temperature forming, forging with high mechanical properties, good surface quality and dimensional accuracy advantages, but the forging of large deformation resistance of low plasticity, illiquid materials, especially high mechanical strength , work hardening sensitive materials forming difficulties. Foreign cold forging technology has been widely used in the production of low-carbon steel, carbon steel and low alloy steel parts by weight of more than a few grams to hundreds of kilograms. Cold forgings used on Japan and Germany car reaches 50kg or more, cold forging our country about 30kg per car around. Production of automotive components are: automobile clutch engagement ring, automotive transmission input shaft parts.
2. Warm Forging Warm Forging (200-850 ℃) has the advantage of cold forging and forging forming. Warm Forging fully inherited the advantages of cold forging high production efficiency, saving raw materials, improve product quality, and low resistance, formability better than cold forging. At the same time, avoiding the disadvantages of forming temperature hot forging energy consumption, prone to overheating, burning, oxidation, decarbonization, allowance, product quality is not high. Currently, Warm Forging Process widely used cold work hardening severely deformed, high deformation resistance, poor cold deformation properties of stainless steel, high carbon high alloy steel, bearing steel, tool steel and other materials. Used in the production of automotive bearing ring.
3, sub-tropical Asian hot forging steel molding (850-1000 ℃) in the accumulation of recrystallization temperature below were avoided when the heating temperature is high coarse grains, oxidation, decarbonization, overheating, burning and other defects. This process reduces the forming resistance, the internal organization has been refined to improve the accuracy of the product, especially to control the deformation temperature, deformation, deformation rate and cooling rate and heat after heat geometric distortion, not only reducing the process and energy consumption, but also alter the mechanical properties of the product. Asian hot forging car CVJ products used for the production of the sleeve.
4, Hot precision forging hot forging process is heated to a rough metal recrystallization temperature within a range appropriate forging temperature forging them on, the heating temperature is high, small deformation resistance, material plasticity and fluidity, forming easier, small tonnage required equipment. Hot precision forging generally used for the production of automotive differential gears, front axle and so on.

The forged parts produced by these three methods takes percentage 80%, 8%, 12%. Typical hot forged crankshaft, connecting rod, constant knuckle pin wheels and gear blanks. Cold forging mainly inner race, cross shaft, input shaft and pinion shaft. Warm forging major outer race, bushings, axle gear and pinion meshing.

Currently, the main task of forging technology is to improve the yield strength of the material, to extend die life net shape forming technology and applications, and the application of CAD / CAM / CAE / CAT technology. This paper describes the net shape forming technology.

Net shape forming technology to produce forgings allowance significantly reduced, which is why is called net shape forming technology. The main purpose is to reduce net shape forming material usage, eliminating some of the machining and improve tooth strength.

General Knowledge on “Axial Flow Hydroponics inline duct fan,Duct Booster Inline Blower Fan ”

 NEVER expose your In-Line Duct Fan to airflow temperatures exceeding 140°F (60°C).

  • Make sure all electrical wiring conforms to all applicable codes and standards. If you are not familiar with electrical installations, consult a qualified electrician.

  • Never use an In-Line Duct Fan for dryer venting.

  • Never connect the High and Low speed wires of a 2-speed In-Line Duct Fan together.

Why do I have a room that is always too cold?
Your problem room may be located far from the furnace. Friction in the long duct reduces airflow to the register in that room, thus delivery of heated air. Also, perhaps the room is over an unheated garage or the duct is simply too small (undersized) to get enough heated air to that room. Remember too, when you are delivering heated air to a room, that air has to have a way to get out of that room. Otherwise there will be no air circulation. Does the room have an air return register? If not, is the door of that room kept closed, stopping air circulation?

Why do I have a room that is always too hot ?
The room that you have a cooling problem with may be far away from the central air system. Long duct runs cause reduction in airflow, plus, the cooled air may have heated up before it gets to the problem room. Perhaps the problem run is to a room on the South side of the house, which has a large window, catching a lot of summer heat. Chances are that your ‘hot’ rooms are on the second level of your home. You see, cooled air is dense and heavy. It doesn’t like to flow upstairs. This is a very common problem, worsened by undersized ductwork and inaccessibility of those ducts. Particularly for upstairs cooling problems, select the largest fan you can fit and use duct diameter expanders & reducers to adapt to the ducts already in place.

What boost can I expect from an In-Line Duct Fan?
A standard floor or wall register is normally fed by a 6″ diameter duct. You would like to boost the airflow from that register because you have a room that is usually cold in the winter or hot in the summer.
The airflow from that register may be as low as 20 or 30 Cubic Feet of air per minute.
Expect this particular example to have double the airflow when an In-Line Duct Fan is installed.

What temperature difference does boosted airflow make?
This is dependent on a host of variables. How well insulated is the room? What heat gain in the summer through a window? How far is the register from the furnace? Is this room over an unheated garage? Etc.
Here is an example:
During the winter heating season, you need a room about 4 °F warmer than it is. To achieve this you will need 11% more airflow out of the register(s) in that room assuming that your furnace runs 60 minutes out of the hour. If your furnace runs 20 minutes out of the hour on a cold winter day, that is 1/3 of an hour. You will need 3 times the 11% or 33% boost. In most applications, an In-Line Duct Fan will boost up to 80%. Thus, well up to the task of warming up a room.

How loud will the installed fan be?
Suncourt fans are rated between 50-60 dBA.

How much power does an In-Line Duct Fan use?
Example: The DB206, 6″ diameter In-Line Duct Fan is rated at 0.35 Amp.
For a 120 Volt product, that is 0.35 x 120 = 42 Watt.
This is the maximum motor STARTING Watts. Once the fan runs, the actual wattage is 27 Watts. Like a small light bulb. In the manufacturers product specifications section, Inductors are listed by Amperage. As a rule of thumb, running Amperage is about 60% of the listed (start) Amperage.
So, to figure it out: Listed Amperage times Voltage (120 Volt) equals startup Watts.
Actual running Watts are about 60% of that.

What type of motors are used in Suncourt products?
The electric motors used in Suncourt products are C-Frame two-pole motors, Class B, Thermally Protected, sleeve bearings and synthetic lubricant. The exceptions are the 400 Series In-Line Duct Fans which have 4-pole, Class B, Thermally Protected motors with sleeve bearings and synthetic lubricant.

Can I use a rheostat or fan speed control with an In-Line Duct Fan?
No. A rheostat lowers the voltage supplied to the fan motor. This will cause the motor to overheat and the Thermal Protector will open, destroying the motor. A solid-state fan speed control could be used. The problem is that such a control allows the fan to be adjusted to very low RPM’s. Since the electric motor needs air flowing over it for cooling, adjusting to too low a RPM will cause the motor to overheat. That will cause the Thermal Protector to open, destroying the motor and voiding the Warranty. Since the speed the motor is adjusted by the user and is not under the control of Suncourt, we advise against using a solid-state motor speed control.

What does Thermally Protected mean?
A thermally Protected motor contains a fuse that will cut off power to the motor should the motor temperature exceed a safe limit. All Suncourt electric motors are Thermally Protected.

What are the fan blades made of?
The 4″-8″ In-Line Duct Fan are equipped with Polycarbonate fan blades. (A high strength superior material as used for jet fighter canopies). The 10″-14″In-Line Duct Fans have aluminum fan blades.

How many Inductor fans can I install?
We recommend that you do not install more than 2 In-Line Duct Fans per 8 registers in your air distribution system. Two boosters will not appreciably affect the airflow to the remaining registers.
If you install more than 2 In-Line Duct Fans per 8 registers, you may be lowering the airflow from a register in some other room in your home, thus creating temperature problems there.

Will an Inductor always double airflow from any register?
No. An In-Line Duct Fan will boost airflow more to a poorly performing register (which is the register needing help) than to a register that already has good airflow. As stated before, a poorly performing register may have double the airflow with an In-Line Duct Fan. A well performing register may have a 30% to 50% percent increase in airflow.

What is the difference between Free Air and Boosted Air?
Free air is the air volume output from a fan, expressed in Cubic Feet per Minute (CFM) when the fan is not connected to any ductwork, pipes, louvers or other items that would interfere with the free flow of air from the fan.
Boosted Air is the maximum airflow that can be passed through an In-Line Duct Fan in CFM before this fan, installed in a duct, becomes a hindrance to airflow rather than boosting an existing airflow.
Depending on the specifics of the electric motor and fan blade combination, Boosted Air can be between 50% to 100% greater than Free Air.

Can I “over boost” a register?
Suncourt In-Line Duct Fans are designed to provide progressive boost. This means that the airflow is proportionally boosted to the need of a particular register. Our booster fans are designed to run at a low RPM in free air. At this RPM, the fan motor runs below the peak torque that can be generated by the motor. Depending on the air blown into the intake side of the In-Line Duct Fan, the RPM will adjust itself as needed to provide boost and will operate at or near peak torque of the electric motor.

In what type of duct can I install an In-Line Duct Fan?
In-Line Duct Fans are suitable for installation in metal, flexible or high density pressed fiberglass ducts. The In-Line Duct Fan can be secured to the duct with screws or a good quality duct tape.

Can I build-in an In-Line Duct Fan, i.e. drywall or panel over it?
No. The In-Line Duct Fan must always remain accessible for service, cleaning or repair.

Can I use the In-Line Duct Fan to vent outside air?
The In-Line Duct Fan has to be protected from rain and excessive moisture.

What is the lowest airflow temperature for an In-Line Duct Fan?
To maintain good oiling of the motor bearings, we recommend a minimum temperature of 40°F (4°C).

What do I typically need for electrical installation?
You will need a small electrical box to mount on the In-Line Duct Fan.
We recommend #8 self piercing sheet metal screws, ½” to 5/8″ long. Be sure these screws do not touch the fan blade or the electric motor.
For this box you will need a power supply strain relief to mount in a “knockout” in the electrical box.
Choose the power cable to conform to the applicable codes and standards. The staff at your favorite Home Center can recommend these materials to you.

Where do I get power from for the In-Line Duct Fan?
Here you have a number of options.
The easiest way to power your In-Line Duct Fan for automatic ON/OFF operation with both your furnace and air conditioner is to use the
Suncourt DuctStat. Please view the DuctStat section of these FAQ’s.
You may power the In-Line Duct Fan via a standard wall switch for manual ON/OFF operation. Running an In-Line Duct Fan continuously will not appreciably affect the life of the fan.
The next best is to connect to the wiring of your furnace. You must connect to the wire that provides power to your furnace blower. Consult the furnace wiring diagram, usually located on the inside of the panel covering the main furnace blower. Again make sure that all wiring conforms to all applicable standards and codes.
Also check that your furnace blower motor has a 110-120 Volt AC motor. Some larger furnaces have 220-240 Volt AC motors. Some of the newest high-end furnaces have DC motors. Do not connect the In-Line Duct Fan to either the 220-240 Volt AC or the DC type.
.
Because of the numerous variations in furnace wiring, ESPEnergy cannot advise you on the hookup.

Can I wire my two-speed In-Line Duct Fan to run on High or Low speed?
Yes, but first this warning. NEVER connect the High and Low speed wires together.
The motor wiring will burn out in a matter of seconds, permanently destroying the unit. Wire to operate either on High speed or Low speed. Never both.
You may use a Single Pole, Double Throw “ON-OFF-ON” toggle, rocker or other switch to wire for High or Low speed operation. This switch must be rated for 125 Volt AC, 10 Amp minimum. Now you can switch your 2-speed Inductor from High to Low speed and have a center OFF position. Connect the supply power to the C (common) terminal, the High speed wire from the motor to the terminal marked 1 and the Low speed wire from the motor to the terminal marked 2. Make sure that the wiring and enclosure for this switch conform to all applicable standards and codes.

Is the In-Line Duct Fan safe?
The In-Line Duct Fans have been rigorously tested to the Standards of Underwriters Laboratories Inc. and proudly display the Listing symbols of both Underwriters Laboratories Inc. (UL®) and Intertech Testing Services Ltd. (ETL®). All Inductors have Thermally Protected electric motors.

Is mainly used for surface coating of steel and steel parts (such as galvanized sheet), widely used in automotive, construction, shipbuilding, light industry and other industries. After the start of the 21st century, the Western countries try to do directly with zinc alloy plate roof covering material, the use of life up to 120-140 years, and then recycled, but for the life of galvanized iron roofing material is generally 5-10 years . After 21 centuries, hot-dip galvanized steel with significant growth. Galvanized also used, but this method is generally used for thin coatings and different surface finish. Coatings containing zinc coating is another way; for the object of continuous contact with water, such as for ships, bridges, and offshore oil and gas derrick large steel components, zinc only, and large blocks of connection, you can be protected, but zinc block should be changed regularly.
(2) zinc alloy for automotive and machinery industries. Zinc has suitable mechanical properties. Zinc itself is not high strength and hardness, but after adding alloying elements aluminum, copper, etc., its strength and hardness are greatly improved, still it is the emergence of zinc and copper alloy, and its mechanical properties have been approached or reached the aluminum, yellow copper levels of gray cast iron, and its creep resistance is also significantly improved. Therefore, zinc and copper alloy has been widely used in hardware production. Mainly for die casting, automotive, construction, part of the electrical equipment, household appliances, toys and other parts production. Many processing properties of zinc alloys are relatively good, pass processing rate of up to 60% -80%. MV superior performance, can be deep-drawing, and having a self-lubricating, extended die life, available brazing or resistance welding or electric arc welding (for an in helium) welding, surface can be plated or coated, good cutting performance. Under certain conditions, with excellent superplasticity. Zinc and copper, tin, lead composed of brass, used in machinery manufacturing. Zinc plate containing a small amount of lead and cadmium and other elements can be made negative zinc-manganese batteries, zinc printing plates, there are pink corrosion photographic system board and offset printing plates.
(3) can be used to produce zinc batteries. For example: manganese batteries and zinc-air batteries latest research.

Zinc has good resistance to electromagnetic properties. Electrical conductivity of 29% zinc standard electrical copper, in the case of RF interference, zinc plate is a very effective shielding material, and because the zinc is non-magnetic, and instrumentation suitable for housing materials and parts instruments coins, Meanwhile, zinc and other metals collision itself and does not spark, suitable for underground explosion-proof equipment. Widely used in rubber, paints, enamels, pharmaceutical, printing, fiber and other industries. Zinc with appropriate chemical properties. Zinc can occur with NH4CI, release H + positive ions. Zinc – is the use of zinc-manganese dioxide battery of this feature, made with zinc alloy battery case, both the battery electrolyte container, also participated in the anode cell reaction constitute battery. It’s this performance is also widely used in the pharmaceutical industry. Zinc and acid or alkali can react hydrogen. Zinc fertilizer (zinc sulfate, zinc chloride) can promote plant cell respiration, carbohydrate metabolism and so on. Zinc, lithopone, zinc chrome yellow pigments can be used. Zinc oxide can also be used in medicine, rubber, paint and other industries.

 General Knowledge on material “Brass”

Brass is an alloy of copper and zinc composed. If only by copper, zinc composition of the brass called ordinary brass. Brass is often used in the manufacture of valves, pipes, air conditioning inside and outside the connecting pipe and radiator.

Ordinary brass. alloy of copper and zinc. When the zinc content of less than 35% of zinc can be dissolved to form a single-phase copper a, known as single-phase brass, plastic, suitable for hot and cold pressure processing.
When the zinc content of 36% ~ 46% of the time, there is also a single-phase β with copper and zinc-based solid solution, called duplex brass, β phase decreases the tensile strength of the plastic to make brass rose, only suitable hot pressure processing
If you continue to increase the zinc content, the tensile strength decreased, no use value
Code with “H + digital” represents, H is brass, numbers indicate the mass fraction of copper.
H68 expressed as the amount of 68% copper, 32% zinc, brass, cast brass in front codenamed “Z” word, as ZH62
Zcuzn38 expressed as zinc content of 38%, the balance being copper, brass casting.
H90, H80 single-phase, golden yellow, it has a total gold Moreover, he called plating, decorations, medals and so on.
H68, H59 brass are biphasic, widely used in structural parts on appliances, such as bolts, nuts, washers, springs, etc.
In general, cold deformation with single-phase brass hot deformation processing phase brass.

Special brass. Adding other alloying elements in general composed of multi-brass alloy called brass. Often adding elements lead, tin, aluminum, etc., and accordingly may be called leaded brass, tin, brass, aluminum and brass. The purpose of adding alloying elements. Mainly to improve the tensile strength improved manufacturability
Code: for “H + main element symbol (except for zinc) + mass fraction of copper + main element mass fraction + other elements mass fraction” said.
Such as: HPb59-1 represents the mass fraction of 59% copper, containing the main element of lead content of 1%, and the balance of lead zinc brass.

Pressure processing performance

α single-phase brass have good ductility (from H96 to H65), can withstand hot and cold processing, but α single-phase brass prone to temperature brittle when hot forging process, the specific temperature range varies with different amounts while Zn the changes, generally between 200 ~ 700 ℃. Therefore, thermal processing temperature should be higher than 700 ℃. The main reason for the single-phase α brass brittle zone temperature is in the Cu-Zn alloy system α phase region exists Cu3Zn and Cu9Zn two ordered compounds, occurs when the low temperature heating and orderly transition, the alloy brittle; in addition , the presence of trace amounts of lead alloys, bismuth harmful impurities form low melting point eutectic with copper film distributed in the grain boundary, resulting in intergranular cracking during hot working. Practice shows that the addition of small amounts of cerium can effectively eliminate temperature brittleness.
Two-phase brass (from H63 to H59), in addition to the alloy has good plasticity α phase, also appeared by electronic compound CuZn-based β solid solution. β-phase having a high plasticity at high temperature, low temperature and β ‘phase (ordered solid solution) hard and brittle nature. Therefore, (α + β) brass should be forged in the hot state. Zinc is greater than 46% to 50% of the β brass due to hard and brittle properties, the pressure can not be processed.

Mechanical Properties

Brass, zinc due to the different mechanical properties are not the same. For α brass, with the increase in zinc content, σb and δ are constantly increased. For the (α + β) brass, when the zinc content increased approximately 45%, room temperature strength continues to increase. If more further increase the zinc content, since the alloy structure appears more brittle r phase (Cu5Zn8 compound-based solid solution), a sharp decrease in strength. (Α + β) brass is always room temperature ductility with increasing zinc content decreases. So more than 45% zinc and zinc alloy no practical value.
Ordinary brass band extremely versatile as tanks, water supply and drainage, medals, bellows, serpentine tube, condenser, shell casings and a variety of complex shape of the red products, hardware and other items. With increasing zinc content from H63 to H59, they could well withstand thermal processing, machinery and electrical appliances used for a variety of parts, stamping parts and musical instruments, etc..

 General Knowledge on material “Copper”

Copper can be divided into: general copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2, and high-purity, oxygen-free vacuum), deoxidized copper (TUP, TUMn), add a small amount of special copper alloy elements (arsenic and copper, tellurium copper, silver and copper) into four categories. Copper electrical and thermal conductivity second only to silver, widely used in the production of electrical conductivity, thermal equipment. Copper has good corrosion resistance in the atmosphere, water and certain non-oxidizing acid (hydrochloric acid, sulfuric acid), alkali, salt solutions and a variety of organic acids (acetic acid, citric acid) in.

Ordinary performance

Comparison of pure copper is a copper, copper generally can be approximated that is, electrical conductivity, plasticity are better, but the strength, hardness some poor. Copper has excellent thermal conductivity, ductility and corrosion resistance. Copper trace impurities have a serious impact on the electrical conductivity, thermal conductivity of copper. Wherein a significant reduction of titanium, phosphorus, iron, silicon and other electrical conductivity, and cadmium, zinc, etc. are little effect. Sulfur, selenium, tellurium and other solid solubility in copper is very small, can generate a brittle compound with copper, the conductive little effect, but can reduce the processing of plastic.
Copper in the atmosphere, water and certain non-oxidizing acid (hydrochloric acid, sulfuric acid), alkali, salt solutions and a variety of organic acids (acetic acid, citric acid), there are good corrosion resistance, for the chemical industry. In addition, copper has good weldability, may be cold, processed into a variety of thermoplastic semi-finished and finished products. 1970s, copper production exceeded the total output of other types of copper alloys.

Physical Properties

Copper trace impurities have a serious impact on the electrical conductivity, thermal conductivity of copper. Wherein a significant reduction of titanium, phosphorus, iron, silicon and other electrical conductivity, and cadmium, zinc, etc. are little effect. Oxygen, sulfur, selenium, tellurium and other solid solubility in copper is very small, can generate a brittle compound with copper, the conductive little effect, but can reduce the processing of plastic. When heated in a hydrogen-containing ordinary copper or a reducing atmosphere of carbon monoxide, hydrogen or carbon monoxide easy cuprous oxide with grain boundaries (Cu2O), thus producing a high pressure steam or carbon dioxide gas, copper can rupture. This phenomenon is often referred to as copper “hydrogen disease.” Oxygen for welding copper harmful. Bismuth or lead generation low melting point eutectic with copper, the copper heat generated brittle; and brittle when a thin film of bismuth was distributed at the grain boundaries, and also allows the copper to produce crisp cold. Phosphorus can significantly reduce the conductivity of copper, but copper solution can increase mobility, improve weldability. The right amount of lead, tellurium, sulfur, etc. can improve machinability. Room temperature tensile strength of annealed copper sheet was 22 to 25 kgf / mm 2 and an elongation of 45 to 50%, and Brinell hardness (HB) of 35 to 45.

 General Knowledge on material “Aluminium”

Aluminum is a silvery-white light metal. Malleable. Goods often made cylindrical, rod, sheet, foil, powder, strip and filamentous. In humid air can prevent the formation of a layer of metal oxide film corrosion. With acid-treated aluminum heat can burn fiercely in the air and emit blinding white flame. Soluble in dilute sulfuric acid, dilute nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water, but hot water may be slowly and aluminum hydroxide produced by the reaction [4], the relative density of 2.70, an elastic modulus 70Gpa, poise loose than 0.33. Melting point of 660 ℃. Boiling point 2327 ℃. Its light, good electrical and thermal conductivity, oxidation resistance and high reflectance is widely used. Daily dish made of aluminum is usually called the “steel fine” or “grades.” Al at (room temperature), the thermal expansion coefficient of 25 ℃ 0.0000236mm / ℃ or 23.6ppm * k-1.
The physical properties of the conductivity of aluminum is approximately 62% copper, 33% copper density. Under the same conditions as the resistor, the volume ratio of copper and aluminum is 0.618, a weight ratio of 2.03. Visible, if the aluminum and copper, respectively, than the diameter of the area and a large 38.2% copper conductors and 21.5%, while only half the weight of copper. Factors affecting the performance of aluminum impurities, such as chromium, lithium, manganese, vanadium. They will greatly reduce the conductivity of aluminum (see figure). Iron, aluminum silicon can be slightly improved tensile strength, but the ductility of the aluminum decrease, increased brittleness. In aluminum fill plus a small amount of magnesium (or other elements) can be made of an alloy, significantly improve the tensile strength and heat resistance. This aluminum conductor steel-reinforced aluminum can be used instead of overhead transmission line conductors. Work hardening of aluminum can improve the tensile strength of aluminum, machining deformation and annealing temperature control can be obtained with a different mechanical properties of hard, semi-hard and soft aluminum. Low temperature aluminum tensile strength, fatigue strength, hardness and elastic modulus increased, nor low temperature brittleness, it is suitable for low-temperature conductors. Since the creep limit and tensile strength of aluminum is temperature dependent. Therefore, long-term working temperature should be below the aluminum element 90 ℃, short-term operating temperature of not more than 120 ℃. Aluminum at room temperature in the air easily oxidized to form a dense and rugged thin film layer, it can prevent oxidation deep inside, play the role of corrosion protection
