  • Lead bronze

Lead bronze is a Cu-Sn-based alloy added with 4-22%Pb to improvebearing performance, in particular.

Symbol Previous symbol Alloy base Characteristics Application example
CAC602 LBC2 Cu-Sn-Pb-based Good pressure resistance and wear resistance Medium-speed, high-load bearings, cylinders, valves, and pressmachine bearings
CAC603 LBC3 Cu-Sn-Pb-based Suitable for bearings with high surface pressure and ensures good conformability Medium- and high-speed, high-load bearings, press machine bearings, and pulverizer bearings
CAC603C LBC3C
CAC604 LBC4 Cu-Sn-Pb-based More conformable than CAC603 Medium- and high-speed, medium-load bearings and vehicle bearings
CAC604C LBC4C
CAC605 LBC5 Cu-Sn-Pb-based Lead-bronze alloy with particularly good conformability and seizure resistance Medium- and high-speed, low-load bearings and engine bearings
CAC605C LBC5C
LBC+Ni2.0 Cu-Sn-Pb-Ni-based Good seizure resistance, and wear resistance Medium- and high-speed, high-load bearings and construction machine bearings
