Electrode for copper and aluminium bronzes CHEM-WELD 902

CHEM-WELD 902

Electrode for aluminium bronzes

DIN 8555: E-31-200c

AWS A 5.6: E CuAlMn-C

Welding current: = +

Welding position: PA, PB, PC

Calcium-base electrode for welding aluminium bronzes, also for welding copper, copper alloys and steel. The weld metal has excellent mechanical properties, is resistant to corrosion, erosion, cavitation and seawater. Due to its properties, it is suitable for ship structures and the chemical industry, especially where both corrosion and erosion act simultaneously. The low coefficient of friction allows it to be rolled onto sliding surfaces. Applications: ship propellers, valves, pumps, shafts, bearing pans, lines, steam condensers, contacts, Kaplan turbine blades, francis turbines, pelton wheels, etc.
