Wei Ouding 204NB low nickel aluminum bronze wire electrode Application Description: especially suitable for welding nickel-copper aluminum alloy casting and forging parts. Applications: marine propeller, the turbine section, bearing, raft doors, screens, pumps, piping, instrumentation engineering and container. On the multi-component alloy steel and copper and aluminum plus layer welding. There are particularly strong resistance to seawater corrosion properties. Abrasion resistance and strong, we recommend using pulsed arc welding in multilayer steel. The physical properties of the deposited metal conductivity: 4.5-5.5sm / mm2 Density: 7.5kg / dm3 solidus: 1030 ℃ liquid line: 1050 ℃ Tensile strength: 450-540N / mm2 Elongation: 30% Hardness: 150HB execution Standard: GB / T9460GB: HSCuAlNi DIN 1733: SG-CuAl8Ni2
