Metal Plating (Cadmium, Tin, Zinc, Nickel, Silver, Copper ...

Cadmium corrosion resistance is very good, especially with Type II finish. Type II shows no corrosion effects after 96 hours of 5% salt spray exposure. Steel parts with UTS of 150,000 psi and above, which are machined, ground, cold formed or cold straightened after heat treatment, may require stress relief before cleaning and plating.

Cadmium poisoning - Wikipedia

Cadmium is a naturally occurring toxic metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where trace quantities of cadmium are found. Cadmium is used extensively in electroplating, although the nature of the operation does not generally lead to overexposure.
