Cobalt is a metallic chemical element which is rather hard and brittle in its pure form. It is used industrially in a number of ways, and is also refined to produce salts and isotopes which have other practical applications. In addition to being an important part of many products, cobalt is also a crucial trace element, necessary for human well being. The grayish, slightly matte element is rarely available in pure form, but it can be found in numerous alloys.
