A Nickel Aluminium Bronze wire for use in welding of Nickel aluminium bronze (Cu Ni Al) components and fittings of similar composition. This weld metal alloy has excellent corrosion and wear resistance characteristics, which promote applications in marine, power and chemical plant components e.g. ships propellers, pumps and sea-water fittings. Surfacing with this alloy on steel or bronze alloy allow a very high corrosion, erosion and cavitation resistance.
