CuAl10Fe5Ni5-C (CC333G) vs CuSn7Zn4Pb7-C (CC493K)
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.
CuSn7Zn4Pb7-C (CC493K)
2.1090
The world's most common bearing bronze (Rg7). Higher tin (7%) and lead (7%) content than Rg5 provides superior bearing properties, better wear resistance, and improved self-lubrication under boundary lubrication. Good sliding properties even for occasional dry running during acceleration. Standard material per DIN 1850/ISO 4379 for plain bearings. Used for medium-load sliding bearings, bushings, guide bushings, valve seats, and worm gear nuts in general engineering, textile machinery, and agricultural equipment. ASTM: C93200.
