ECuAl-A2 Aluminum Bronze A-2 Welding Rod Application

ERCuAl-A2 filler metal is an iron-bearing aluminum bronze and is generally used for joining aluminum bronzes of similar composition: manganese, silicon bronzes, some copper-nickel alloys, ferrous metals and dissimilar metals. The most common dissimilar metal combinations are aluminum bronze to steel and copper to steel. This alloy also is used to provide wear- and corrosion-resistant surfaces.

ERCuAl-A2 Aluminum Bronze A2 is a very versatile bare wire. It is used for joining aluminum bronze of similar composition, silicon and manganese bronze, high strength copper-zinc alloys, some copper-nickel alloys, ferrous metals and dissimilar metals. Dissimilar applications include aluminum bronze to steel and copper to steel. It is also used for building up or overlaying metal for wear and corrosion resistant surfaces. Aluminum Bronze A2 is most commonly used for marine maintenance and repair welding of ship propellers, pump housings, rigging jacks, piston heads, bearings and many overlay or surfacing applications.
