Development of Cadmium-Free Silver Metal-Oxide Contact Materials
A cadmium-free silver-base alloy has been developed to substitute the standard Ag-12% CdO contact alloy which is widely used in electrical and electronics industries. Substitution of cadmium was attempted through the addition of zinc as the basic and major alloying element and with minor additions of tin and copper. The developed alloy, after internal oxidation, possesses better electrical contact characteristics than the standard alloy.
