HL201 phosphor‑copper flat brazing rods 3.2mm wide 1.3mm thickness 500mm long

HL201 phosphor‑copper flat brazing rods, intended for brazing copper and copper alloys, especially in refrigeration, air‑conditioning, electrical and instrument assembly. It highlights the 1.3 mm × 3.2 mm × 500 mm flat‑rod form, low‑melting composition and approximately 60 rods per kilogram.

NOTE: Oxy‑acetylene welding, argon‑arc welding or flame guns are all acceptable. For outdoor air‑conditioning and refrigeration copper pipe repair, this flat rod size is commonly selected. Standard length is 0.5 m.

Performance

Product Name	Phosphor‑Copper Brazing Rod
Model	HL201
Melting Point	710 °C–793 °C
Chemical Composition	P: 7.0–7.5%, Remainder: Cu / Copper
Tensile Strength	500 MPa
Elongation	3%
Properties & Applications	Suitable for brazing copper and copper alloys, widely used in electrical, instrument, refrigeration and air‑conditioning industries. No extra brazing flux is required when brazing copper. Flux should be used when brazing copper alloys.

Core Features

1. Phosphor‑copper formula with 7.0–7.5% phosphorus and copper as the remainder.
2. Low melting range of 710–793°C, suitable for controlled copper brazing.
3. Flat rod geometry: 1.3 mm × 3.2 mm × 500 mm, easy to feed into joint gaps.
4. Approximately 60 pieces per kilogram, supporting cost estimation and bulk purchasing.
5. High tensile strength of 500 MPa for strong copper joints.
6. Self-fluxing on copper: no extra brazing flux needed for copper-to-copper work.
7. Requires flux on copper alloys for cleaner wetting and stronger joints.

Typical Application Scenarios

1. Refrigeration and HVAC technicians: Brazing copper pipes, air‑conditioning joints and refrigeration system repairs.
2. Electrical component manufacturers: Joining copper conductors, terminals and copper busbars.
3. Instrument and meter assembly: Brazing thin copper parts requiring low‑melting filler metal.
4. Copper pipe installation contractors: Repairing and connecting copper tubing in HVAC systems.
5. Maintenance workshops: Performing outdoor air‑conditioning and refrigeration service repairs.
