Introduction:

AWS A5.7 ERCuNiAl. It is a nickel-aluminium bronze alloy used to weld cast and wrought. With Ni and Fe addition. Weld cladding on cast iron materials and steel. Mixed joints of aluminium bronze steel. It is resistant to seawater and cavitation resistant. Good suitability for simultaneous stress-strain caused be seawater, cavitation and erosion.

Application:

Recommended for the joining and overlaying of copper-aluminium alloy, aluminium coated steel in machinery and chemical industry as well as for iron welding in shipbuilding. Also excellent for the join welding of brass tube and copper-aluminium that requires resistance to erosion.
Include ship fittings, ship propellers, power plant valves, piping systems, intake screens, oil recovery pumps, and propeller gear housings
