Cobalt - Wikipedia

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.

Allergy to cobalt | DermNet NZ

Cobalt allergy is diagnosed from the clinical history and by performing patch tests. Nickel and cobalt are always found together in alloys and salts because it is too costly and impracticable to separate these two metals. Thus patch testing should always include both cobalt and nickel.
