Characteristics and Properties of Copper and Copper Alloy ...

Copper-lead alloys containing about 30% lead are stronger but have less satisfactory surface properties and are usually used with a thin lead-tin overlay. If the copper-lead alloys do not have sufficient load-carrying capacity, the lead content is reduced, and tin is added to improve the strength. Typical is a 74Cu-22Pb-4Sn composite.
