Brass Brazing Alloy

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. Contaminantes on the surface, such as grease and oxides must be removed thoroughly before brazing. Addition of flux is necessary during brazing in order to obtain optimal brazed joints.

This brass brazing alloy contains relatively high level of Ni, which can improve the plasticity of the alloy and the wettability of the brazing filler metal on cemented carbide. It is especially suitable for brazing cemented carbide, and can be used for brazing applications with high corrosion requirements, such as the brazing of steels and nickel alloys.
