What's the Difference Between Cadmium and Zinc Nickel Plating?

Zinc-nickel electroplating provides a protective, sacial coating, just like cadmium. It also offers excellent corrosion resistance and ductility. However, a major difference between the two plating metals is that zinc-nickel has high hardness and is resistant to high temperatures, while cadmium is soft and not as heat-resistant.

Cadmium Plating

In order to provide long-term galvanic corrosion protection for steel parts contacting other aluminum parts we'd like to plate steel parts with cadmium (already having alodine coating on aluminum). Also, these steel parts are of high precision and must withstand very high loads, so originally we make them from SS 17-4PH Condition H900.


Cadmium

Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite.
