ALUMINUM BRONZE A-2 Alloy

AWS A5.7 Class ERCuAl-A2
ASME SFA5.7 ERCuAl-A2

Washington Alloy Aluminum Bronze A-2 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. Washington 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. 

Applications:

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.
