AK-ERCuZn-B (TIG / MIG)

Standard： 

EN ISO 24373 CuZn40Ni

AWS A5.7 ERCuZn-B

GB/T 9460 CuZn40Ni

Application: Brass welding wire containing a small amount of iron, silicon, and manganese has good fluidity of molten metal. Due to the existence of silicon, it can more effectively inhibit the evaporation of zinc. It can be used for gas protection of copper, steel, copper-nickel alloy, and gray cast iron. Argon arc welding, and inserting carbide tools. It needs to be preheated at 400-500°C before welding.
