CuAl8Ni2 Nickel-Aluminum Bronze Welding Wire

CuAl8Ni2 Nickel-Aluminum Bronze Welding Wire APPLICATION

CuAl8Ni2 Wire electrode used for copper aluminum alloys with Ni and Fe addition. Weld cladding on cast iron materials and steel. Mixed joints of aluminum bronze steel. CuAl-wire/rod for joining copper-aluminum alloys (7-9% Al) containing Nickel Manganese and Iron. Applications include overlaying of steel. Suitable for welding on cast iron.

It is resistant to seawater and cavitation resistant. Good suitability for simultaneous stress-strain caused be seawater, cavitation, and erosion

CuAl8Ni2 is a nickel-aluminum-bronze alloy used to weld cast and wrought nickel-aluminum bronze. It has excellent resistance to corrosion, erosion, and cavitations in salt or brackish water.Its applications include ship fittings, ship propellers, power plant valves, piping systems, intake screens, oil recovery pumps, and propeller gear housings.
