ERCuAl-A1 Aluminum Bronze Welding Wire APPLICATION

ERCuAl-A1 Aluminum Bronze Welding Wire is an iron-free, aluminum bronze alloy available in spooled wire and 36” bare-filler metal rod for use with the gas metal arc and gas tungsten-arc welding processes respectively.

ERCuAl-A1 Aluminum Bronze Welding Wire deposits are used primarily to overlay bearing and wear-resistant surfaces requiring a hardness of approximately 125 BHN and to resist corrosion especially from salt water, metal salts, and many commonly used acids in varying concentrations and temperatures. This alloy is not recommended for joining since the deposit does not have a tendency to be hot short.

ERCuAl-A1 Aluminum Bronze Welding Wire applications include tube sheets, valve seats, pickling hooks, impellers, chemical plants, and pulp mills. Welding in the flat position is preferred. Welding in other positions can be done successfully with pulsed arc welding equipment and welder technique.
