Cadmium Overview Occupational Safety and Health

Electroplating, metal machining, welding and painting are operations associated with cadmium exposure. Workers involved in landfill operations, the recycling of electronic parts, or the recycling of plastics may be exposed to cadmium. Compost workers and waste collectors are also potentially exposed to dust which may contain cadmium.

Cadmium Plating Chem Processing Inc.

Cadmium Electroplating (Nadcap Accredited). Electroplated cadmium is a robust and versatile metallic coating. Cadmium is a soft white metal that, when plated onto steel, cast iron, malleable iron, copper, and powdered metal, functions as a "sacrificial coating," corroding before the substrate material.

Cadmium Wikipedia

Cadmium is a component of some compound semiconductors, such as cadmium sulfide, cadmium selenide, and cadmium telluride, used for light detection and solar cells. HgCdTe is sensitive to infrared [38] light and can be used as an infrared detector, motion detector, or switch in remote control devices.

Cadmium Plating milinc

Racking of detailed machined parts can be challenging in throwing cadmium into deep bores requiring complex conforming anode fixturing. Barrel cadmium plating can be utilized on small, non-critical parts when allowed by specification. Barrel rotational speed is limited to 7 RPM leaving the parts free of rack marks, nicks and dings.

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.
