Introduction:

AWS A5.7 ERCuAl-A2. ERCuAl-A2 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.

Application:

Marine maintenance and repair; wear surface reconstruction; cast repair; joining aluminum bronze of similar composition.
