CuAl10Fe5Ni5-C (CC333G) vs CuSn5Zn5Pb5-C (CC491K)
Side-by-side chemical composition and mechanical property comparison.
Overview
CuAl10Fe5Ni5-C (CC333G)
2.0975
Cast 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.
CuSn5Zn5Pb5-C (CC491K)
2.1096
Classic leaded gunmetal (Rotguss Rg5) — the universal copper casting alloy for bearings and fittings. 5% Sn + 5% Zn + 5% Pb provides good machinability, moderate strength, excellent corrosion resistance in fresh and sea water, and self-lubricating properties from lead phase. Used for plain bearings under low/medium loads, valve bodies, pump housings, pipe fittings, and general marine hardware. The economic workhorse of the bronze foundry. ASTM: C83600 (SAE 40), BS: LG2.
