Can be used for brazing and for the Oxy-Fuel Gas Braze-Welding process, with liquid flux spread through the torch flame. Brass Brazing Alloys are mainly used for welding among copper, steel and iron. Most of the common (and easy to use) brazing alloys. It’s a low cost and good physical ability brazing alloy for brazing carbon steel, cast iron, hard carbide tools etc. Brass brazing alloys are widely used in bicycle frame, diamond tools, metal process, marine repair industries. BEIDUO Alloys offers an extensive range of copper and silver brazing alloys to suit your welding applications, a wide variety of brazing, welding and soldering alloys for joining most applications encountered in the field.
