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 coppers 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.
