Bluefire phosphor-copper brazing alloy is a material with the binary alloy of copper-phosphors base, which has good mobility, low cost ones and processing property. It applies to contact welding, gas flame welding, HF brazing and some furnace welding. Phosphor-copper brazing alloy has self-brazability and doesn't need brazing flus. But flux is required while brazing brass to brass.

|7.5-8.1||<=0.15||1310/710||1418/770||Close to eutectic crystay compositio low melting point, easy flow into a small clearance of brazing seam.||Use for copper and copper alloy parts, refrigeration compressor, not suitable for brazing attacking shocking bend parts.|
|6.6-7.4||<=0.15||1310/710||1508/820||Contain less phosphors. has better plastic nature, a little higher melting point.||Use for copper and copper alloy parts, suitable for air conditioning, refngerator evaporator, heat eschanger and water heater ect.|
|JCuP C||6.1-6.8||<=0.15||1310/710||1508/820||Contain a little phosphorus. has better plastic nature, a little higher melting point.||Can make into many kinds of brazing ring, wires, brazing copper and copper brazing ample clearance tie-in.|
