CuAl10Fe5Ni5-C (CC333G) vs Cu-ETP
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.
Cu-ETP
CW004A
Electrolytic Tough Pitch copper — the most widely used copper grade worldwide. 99.90% Cu min with controlled oxygen content (~0.02-0.04%). Electrical conductivity ≥100% IACS. Used for busbars, motor windings, transformer coils, electrical conductors, roofing, and radiators. Caution: hydrogen embrittlement risk in reducing atmospheres above 370°C.
