Cu-P and Cu-P-Ag welding material

Intermediate Temperature Brazing Alloy

Cu-P and Cu-P-Ag welding material:

Cu-P and Cu-P-Ag welding material is a kind of Copper and Phosphor alloy, which used in soldering copper and copper alloy with excellent performance. When soldering the high purity copper, the flux is unnecessary. The soldering joint is with higher strength, so it is widely used in the refrigeration equipment such as air-condition, refrigeratory etc and electric industry. What’s more, it can be replace silver solder under more situation used in soldering copper and copper alloy.Cu-P-Ag welding material is added silver on the basics of Cu-P welding material, which not only better joint plasticity, physical and artwork performance, but also improve tensile strength and lower melting point, is available in fine electrical conductivity, wetting and filling clearance ability. We produce the following Cu-P and Cu-P-Ag welding materials:
