High Quality Phosphor Copper Brazing Rods from China Factory - Reliable Suppliers for Copper Brazing Alloys
Material
Cu, P.
Advantages
Easy to install and disassemble: Good fluidity during welding, can flow into small spaces.
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.
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.
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
This copper brazing alloy is primarily composed of Copper (Cu) and Phosphorus (P), with phosphorus content ranging between 6.1% and 8.5% depending on the specific product code (JCuP-1, JCuP-2, JCuP-3).
No, when brazing copper to copper, the phosphorus inside the alloy acts as an active brazing flux. However, a suitable flux may be required when brazing brass or bronze joints.
The BCuP-2 (JCuP-2) alloy has a solidus temperature of 710°C (1310°F) and a liquidus temperature of 800°C (1472°F), providing excellent fluidity and performance under gas flame heating.
They are ideal for HVAC, plumbing, and mechanical repairs. Typical applications include brazing copper and copper alloy joints in air conditioners, freezers, heat exchangers, evaporators, and water heaters.
Yes. While we offer standard flat, square, and round sizes (such as 1.3x3.2x500mm, 3.2x3.2x500mm, and 2.0x500mm), customized dimensions can be manufactured according to specific customer requirements.
We use standard seaworthy export packaging: products are wrapped with polyethylene film including a drier, then packed into PVC bags (5kg or 5.67kg) and secured in carton boxes (10kg or 11.34kg).
