High Quality Phosphor Copper Brazing Rods - China Factory Suppliers for Efficient Copper Joining Solutions
Material
Cu、P.
Advantages
- 1 Easy to install and disassemble: Good fluidity during welding, can flow into small spaces.
- 2 Moderate melting point: Good fluidity during welding, perfect performance under gas flame, induction and furnace brazing methods, outstanding oxidation resistance at high temperature, excellent corrosion resistance and fatigue resistance after welding, suitable for high temperature and high pressure environment.
- 3 Good joint strength and conductivity: It can quickly transfer heat and achieve precise temperature control, ensuring stable and efficient welding process, perfect for MAPP, MAP, propane and oxygen acetylene gas welding gun settings.
- 4 No need to use brazing flux: When brazing copper with copper-phosphorus brazing alloy, the phosphorus in the brazing alloy plays the role of brazing flux.
Application Scope
A popular and economical solution for HVAC, plumbing and mechanical repairs, used for brazing of copper and copper alloys in motor, instrumentation and refrigeration industries, very suitable for gas welding, contact welding and some furnace welding, suitable for brazing copper to copper, brass and bronze joints in air conditioners, freezers, evaporators, heat exchangers, water heaters, etc.

Frequently Asked Questions
A1: These alloys are composed of Copper (Cu) and Phosphorus (P).
A2: No extra flux is required. When brazing copper with this copper-phosphorus alloy, the phosphorus content within the alloy itself plays the role of the brazing flux.
A3: They are widely used for HVAC, plumbing, and mechanical repairs. They are suitable for brazing copper and copper alloys in motor, instrumentation, and refrigeration industries, including air conditioners, freezers, evaporators, heat exchangers, and water heaters.
A4: The standard sizes include Flat (1.3x3.2x457mm / 1.3x3.2x500mm), Square (3.2x3.2x500mm), and Round (1.5x500mm / 2.0x500mm / 3.0x500mm).
A5: Yes. While standard sizes are readily available, other custom sizes can be produced according to specific customer requirements.
A6: The standard export seaworthy packing includes a polyethylene film with a drier inside. It is packed either as 5.67kgs/pvc bag (11.34kgs/carton box) or 5kgs/pvc bag (10kgs/carton box).
