ERCuAl-A2 Aluminum Bronze Welding Wire Application

ERCuAl-A2 Aluminum Bronze Welding Wire is a very versatile alloy available in coated electrodes or 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. ERCuAl-A2 Aluminum Bronze Welding Wire 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.

Aluminum Bronze A-2 (ERCuAl-A2) filler metal is an intermediate-strength aluminum bronze alloy used for welding aluminum bronze plate fabrications and for joining dissimilar metals such as cast iron, carbon steels, copper,bronze and copper-nickel materials. It is excellent for building up or overlaying metal for wear and corrosion resistant surfaces.

Weld deposits exhibit high mechanical properties, tensile strength, yield strength and hardness.

Particularly suitable for the hard-facing of Aluminum Bronze with steel. It has increased resistance to wear and abrasion, as well as superior corrosion resistance to seawater. Widely used for ship constructions, apparatus and plumbing. For multi-layer hard facing on steel, pulsed Argon arc welding is recommended.
