The welding of copper with Cu-Sn alloy. Best for the butt joining welding of brass with steel. Pre-heat suggested for the large size products, and pulsed argon arc welding is recommended for multilayer hard facing on steel.
CuSn10 phosphor bronze has high strength, good elasticity and wear resistance, corrosion resistance and easy welding and brazing characteristics, while having good electrical conductivity, not easy to heat, to ensure safety. This material has good corrosion resistance in the atmosphere and fresh water, and has high strength and excellent cutting properties
