Cast Copper-Lead Alloys (Leaded Coppers) are copper alloys, containing 24-51% of lead (Pb) as the major alloying element. Cast Copper-Lead alloys are designated with the numbers from C98000 through C98999.
Cast Copper-Nickel alloys may contain up to 3% of tin (Sn), and up to 5% of silver (Ag) as additional alloying elements.
Cast Copper-Lead alloys possess binary microstructure, consisting of lead particles distributed throughout the copper matrix.
Lead in the Cast Copper-Lead alloys serves as a solid lubricant in sliding friction applications.
Cast Copper-Lead alloys are used for manufacturing sliding bearings, bushings and other sliding friction components.
