Zinc plating became popular when in 1933 the automotive industry took up the cadmium bearing. They bought up all but about 40% of the available cadmium. Cadmium plating had been useful for corrosion resistant applications. The result was a shortage and high price of cadmium. The alternative was to use zinc for corrosion protecting applications.

Cadmium plating is a type of coating process that offers technical benefits such as outstanding corrosion resistance, even in high-salt and low-thickness environments. Cadmium is the byproduct of the production of zinc, and it was only in 1920s that cadmium plating was recognized as a form of protective coating.
