S211 copper welding wire HSCuSi silicon bronze welding wire ERCuSi-A copper alloy welding wire SG CuSi3 welding wire Cu6560
Application description: Welding and overlay welding of copper zinc alloys and low copper alloys. The overlay welding of low-alloy steel, non alloy steel, and cast iron has excellent wear resistance and is suitable for MIG welding of galvanized sheets. Suggest preheating when used for large-area TIG welding; When welding multiple layers of steel, pulse arc welding is used.
