ERCuAL-A3 Aluminum Bronze contains a higher Iron (Fe) content than Aluminum Bronze A-2. The higher Iron content gives “A-3” greater strength when joining aluminum bronze castings of similar composition. “A-3” is often used for piston overlay and bearing surface applications which require higher strength, while maintaining good ductility

ERCuAL-A1 Aluminum Bronze is an iron-free aluminum bronze filler metal used for MIG and TIG overlay welding of bearing and wear resistant surfaces exposed to corrosive environments such as salt or brackish water and commonly used acids. Aluminum Bronze A-1 is not recommended for joining. Commonly used in steel and pulp mills to overlay tube sheets, valve seats, and refineries.

Applications:
ERCuAL-Ni Aluminium Bronze is used to join and repair wrought and cast nickel aluminium bronze materials. It is best for the fabrications or repair of shipbuilding and propellers, power plant valves, oil recovery pumps, Piping system and other components subject to salt and brackish water.

ERCuAL-A2 Aluminum Bronze is an iron-bearing MIG and TIG filler metal 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 metal combinations would include aluminum bronze to steel and copper to steel. Alloy Aluminum Bronze A-2 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. Most common applications would include marine maintenance and repair welding of ship propellers; pump housings, rigging jacks, piston heads, bearings and many overlay or surfacing applications.
