The melting temperature of Cu-based non-phosphorus filler metal is higher. Commonly used for brazing carbide, stainless steel and alloy copper base brazing filler metal, mostly based on copper zinc alloy, adding manganese, nickel and other elements to improve its brazing strength, is a brazing carbide performance of better brazing filler metal. Copper base phosphorus containing filler metal, phosphorus content is the key to determine the melting range and performance, can be used as a self-soldering agent in the welding of copper and copper, without adding flux, with good fluidity. However, when brazing brass and bronze, it is necessary to cooperate with the flux. According to the market demand, phosphorus copper filler metal with various composition ratio can be provided.
