Aluminum bronze alloy used for welding steel and cuprallumini, i.e. copper-aluminium alloys.
It is excellent for cladding
components undergoing metal to metal wear and for corrosion
resistant surfaces. Especially suited for marine environments: the addition of nickel improves corrosion resistance in seawater even with cavitation and heat. Applications
include tube sheets, pickling hooks, impellers, valve seats,
chemical plants, pulp mills.
