CuMnAl
Description
Copper rod alloyed with nickel-aluminum
This rod is particularly suitable for corrosion-resistant overlay welding on cast iron and on non-alloyed and low-alloy steels. It deposits a copper, aluminum, and manganese alloy free of zinc, characterized by high hardness and tensile strength. It can be used for mounting copper on aluminum, for overlays on steels and cast iron, as well as for cavitation-resistant overlays. The manganese-nickel-aluminum bronze is also suitable for welding joints resistant to seawater, particularly to withstand erosion, corrosion, and cavitation, and for overlays on copper alloys, carbon-manganese steels, and cast iron.
