CuAl10Fe5Ni5-C (CC333G) vs CuZn39Pb3
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.
CuZn39Pb3
2.0401
The most widely used free-cutting brass (machinability index 100%). Excellent for high-speed automatic lathe work. Used for turned parts, faucets, valves, fittings, screws, nuts, electrical connectors, and watch components. Also known as MS58.
