BCuP-5 is a filler metal with high copper content, self-soldering property, excellent processability, good electrical conductivity and low price. With the self-fluxing effect of phosphorus, no additional flux is needed when brazing pure copper with phosphor copper, while flux must be used together when brazing brass and bronze. It is widely used for brazing copper alloy parts in industries such as refrigeration, motors and instruments. The brazing methods can be flame brazing, furnace brazing, induction brazing, resistance brazing, etc. The specific parameters are as follows
