Copper-Zinc Brazing Filler Metals

Copper-zinc brazing filler metals are mainly used in fast-heating brazing processes such as flame brazing, high-frequency induction brazing and resistance brazing. It is used to braze copper, copper alloys, steels, cast iron, and cemented carbide. Contaminants on the surface, such as grease and oxides must be removed thoroughly before brazing. Addition of flux is necessary during in order to obtain optimal brazed joints. Such as RCuZn-A, the product contains Sn and Si, which can improve the wettability of the brazing alloy and prevent the volatilization of Zn during brazing.
