17-4-4 lead bronze

Cast lead bronze is a type of cast copper alloy with added elements such as tin (Sn) and lead (Pb), typically classified as leaded tin bronze. This type of material possesses excellent wear resistance, corrosion resistance, and machinability, and is widely used in industrial components such as bearings, bushings, valves, and pump bodies. When the material is in bar or pipe form, it is usually produced using continuous casting or centrifugal casting processes, resulting in products with a dense structure and uniform properties.
