Phosphor bronze is a Cu-Sn-based alloy with added P to improve tensile strength, hardness, and in particular, bearing performance.
|Symbol||Previous symbol||Alloy base||Characteristics||Application example|
|CAC502A||PBC2||Cu-Sn-P-based||Good corrosion resistance and wear resistance||Gears, worm wheels, bearings, sleeves, impellers, wear-resistant plates, general and mechanical parts|
|CAC503A||–||Cu-Sn-P-based||High hardness and good wear resistance||Sliding parts, hydraulic cylinders, sleeves, gears, and wear-resistant plates|
|PBC+Ni1.5||–||Cu-Sn-P-Ni-based||Higher mechanical strength than JIS-conforming phosphor bronze||Worm wheels and bearings|
|PBC+Pb1.0||–||Cu-Sn-P-Pb-based||Machinability is better than JIS phosphor bronze system||Wear-resistant plates and bearings|
