34% COPPER ALLOY SILVER BRAZING ROD 

HUAZHONG HZ-Ag34BSn is a cadmium free silver brazing filler metal. It exhibits poor / sluggish flow characteristics melting over a 100°C temperature range. Because of these characteristics HZ-Ag34BSn is not widely used today.

HZ-Ag34BSn has an ability to fill gaps that cannot be tightly controlled and to build fillets. Optimum joint gaps at brazing temperature are 0.075-0.2mm.

Product uses: 

This filler metal can be used to join all the common engineering materials (excluding aluminum) – such as copper, copper alloys (including, brasses, bronzes, gun metal, nickel silvers, aluminum bronze, copper nickel) and steel (including, mild, carbon, tool steel, stainless steels and low alloy steel). It may be used for brazing tungsten carbide and PCD segments however where cracking of the carbide or wetting of the filler metal may be an issue specialized silver brazing filler metals containing nickel / manganese are often preferred.

Conditions for use: 

This filler metal is mainly used for brazing in air with a flux. In most cases HZ-QJ102 and HZ-QJ305 flux can be used in conjunction with HZ-Ag34BSn. However, flux selection is application dependent. Please refer to HUAZHONG technical department or flux product data sheets before selecting a flux.
