Rhodium


Rhodium, a precious metal, is white in color meaning it is non-oxidizing. It is well suited for plating of parts such as sliding electrical contacts that require protection from corrosion or galling. Rhodium is a bright, attractive finish that is non-tarnishing. When underplated with nickel it provides a mirror surface that is highly reflective. Below is the most common specification for rhodium plating.
