Copper balls are widely used in conductive, electrical-contact and specialized industrial applications requiring high electrical conductivity, ductility and non-magnetic performance.

Copper alloy balls include brass balls and copper balls used in applications requiring conductivity, corrosion resistance, stable metallic appearance and non-magnetic performance.

Brass balls are widely used in valve, hardware, decorative and general industrial ball applications requiring corrosion resistance, machinability and stable metallic appearance.
Common brass ball materials include H62 (CuZn38 / C27200) and H65 (CuZn35 / C26800) brass alloys.
