Uses

Because it is corrosion-resistant, chromium is used in alloys, including stainless steel. (Stainless steel also contains Iron and Nickel.) It is also used to plate metal parts.

The word chromium comes from a Greek word meaning color. As you might imagine, Chromium compounds have many different colors. Like all transition metals, the colors of these compounds are caused by d-shell electrons. Emeralds and rubies are colored because of small amounts of Cr3+. Pigments account for approximately 35% of chromium compounds made annually.

Availability

Chromium can be found in deposits in southern Africa, the Phillipines, and Russia.
