Aluminium Brazing Rings

Aluminium Brazing Ring is a welding ring that container magnesium aluminum filler metal. The weld deposit of this filler metal offers good corrosion resistance when exposed to salt water. This alloy is commonly used on base metals 5050,5052,5083,5356,5454 and 5456. The post-anodizing color tint of the weld area is white.

TYPICAL MECHANICAL PROPERTIES

Tensile strength:269 MPa

Yield strength:132MPa

Elongation:17%

Melting Point:571-635°C

Processing Temp.:600-645°C

Thermal Conductivity:~100W/m°C

27.7%IACS

Electrical Resistivity:~6.0µΩcm

~28%IACS

Welding Process:MIG,TIG

Anodizing: Excellent

Corrosion Resistance: Excellent. Very good in marine atmosphere

Conductivity: Poor

Chemical Composition (%):

Cu1.8-2.2, Mg4.5-5.5,other<0.5, Al:bal.(There are different composition for different models of Aluminium Brazing Ring )

APPLICATION

Parent Metals:5000 series alloys(AlMg) with Mg<4%,6000(AlMgSi) alloys when anodized. Cast alloys of AlSi-Mg type. In practice the most versatile and universally used filler metal.

13.0-17.0 605-765 Have good fillet forming properties with ability to bridge wide gaps. Their wide melting range limits their applications. Due to their wide melting range they are somewhat more subject to liquation and may require more care during brazing. Therefore, they are not normally recommended for applications with slow heating rates.
