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|
|CAC604||LBC4||Cu-Sn-Pb-based||More conformable than CAC603||Medium- and high-speed, medium-load bearings and vehicle bearings|
|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|
|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|
