CuAl10Fe5Ni5-C (CC333G)
2.0975Cast nickel aluminium bronze — the premier marine copper alloy. 10% Al + 5% Fe + 5% Ni provides exceptional strength (UTS >600 MPa), outstanding seawater corrosion/erosion/cavitation resistance, and excellent anti-galling properties against stainless steel. Heat treatable for enhanced corrosion resistance. Retains properties at cryogenic temperatures. Used for marine valve bodies, pump impellers, propeller hubs, gear wheels, heavy-duty bearings, and offshore structural components. ASTM: C95500/C95800, BS: AB2.
