CuAl10Fe5Ni5-C (CC333G) vs CuFe2P
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.
CuFe2P
CW107C
Precipitation-hardened copper-iron alloy — THE semiconductor leadframe material since 1964. Fe precipitates give UTS up to 580 MPa while maintaining 60-65% IACS electrical conductivity. Resists softening to 350°C (critical for IC packaging). Also used for automotive connectors, pin grid arrays (PGA), and terminals. Trade names: Wieland K65, Aurubis PNA212.
