Leaded Bronze

The high lead component provides excellent dry running properties and gives a lower hardness. The mechanical properties change at an operating temperature above 200°C. Leaded bronze is suitable for bearings with a high surface pressure, is acid resistant and can even be used with water lubrication. Leaded bronze is available in the alloys CuSn10Pb10 (CC495K) and CuSn7Pb15 (CC496K).
