Copper Brazing Powder
Copper based brazing materials are based on copper and added with elements that can reduce the melting point and improve its comprehensive properties, such as phosphorus, silver, zinc, tin, manganese, nickel, cobalt, titanium, silicon, boron, iron, etc., mainly including copper, CuP, Bronze, Brass, CuMn, etc. Copper based brazing materials is widely used in brazing of copper and copper alloy, carbon steel and cast iron, stainless steel, high temperature alloy, cemented carbide, etc. it has good conductivity, heat conduction, strength and corrosion resistance.
