C16200 Cadmium Copper

CuCd1-UNS.C16200 Cadmium Copper alloy offers a unique combination of high tensile strength and high electrical conductivity for an industry where these properties are generally considered incompatible. The nominal composition of 99.0% copper and 1.0% cadmium can lead to these unique properties.
The cadmium noticeably increases the copper's strength and resistance to softening and stress relaxation with minimal decrease in its electrical conductivity.  It also produces an alloy noted for its malleability and toughness and spring quality.
