UNS C22000 Composition
Bronze UNS C22000 is composed of 88% to 90% copper and 8% to 10% zinc. It also contains 0.05% of lead, which aids in its machinability. The presence of copper gives the material its characteristic reddish-brown colour and excellent electrical conductivity. On the other hand, the zinc content enhances the material's strength and corrosion resistance.
