CuAl10Fe5Ni5-C (CC333G) vs CuBe2
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.
CuBe2
CW101C
THE highest-strength copper alloy — UTS up to 1400 MPa (200 ksi), approaching steel strength with copper's conductivity (22% IACS aged). Age-hardenable: solution treat 780-800°C, age 315-340°C → HRC 38-45. Non-sparking, non-magnetic. Trade names: Alloy 25 (Materion), BeCu25 (NGK). CAUTION: Be dust is carcinogenic — machining requires extraction. Used for non-sparking tools, mold inserts, springs, connectors, and resistance welding electrodes.
