Phos-Copper Brazing Alloys
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.

| JCuP A | BCu92P TC-310D | 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. | ||
| JCuP B | BCuP-2 TC-310A | 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. | |||
