Cadmium metal is soft and malleable when pure and is used mostly for electroplating steel (corrosion resistance) and in the manufacture of bearings. Cadmium compounds are also found in oil paints where they provide some brilliant colors (e.g., "cadmium yellow"). In its solid state, this metal is a silvery grey color. Cadmium is a very good electricity conductor, as well as very resistance to corrosion, making it an excellent sacrificial anode for metals such as iron and steel.
Like zinc and tin, cadmium metal "cries" or emits a high pitched sound when bent rapidly. Most cadmium today is recovered as a by-product of the zinc refining process.
