Features: Copper and copper alloy welding wires are in wide use and can be used toweled sorts of copper alloy, especially brass welding wires are widely used to braze carbon steel, cast iron, hard carbide tools and so on. Because of the good corrosion and wear resistance, people use them to weld the parts easily effected form wear between metals and the parts easily corroded by seawater, such as bearing, valve, sealing surface and so on. When oxy-acetylene flame gas welding, the brass welding should use together with the copper gas welding (CJ301)melting agent Acetylene.
