Cadmium Substitutes

There is increased pressure, both domestically and internationally, for reduced usage, or even elimination of cadmium plating for health, safety, and environmental reasons. There have been several zinc alloy baths developed that work for specific applications, but none duplicates all the properties of cadmium. There are many instances, however, where the use of cadmium plating is not essential and zinc or zinc alloy deposits could be substituted, because both give adequate anodic protection, and there was no functional purpose when cadmium was chosen in the first place.
