    Background Cobalt compounds have been used for centuries to provide a rich blue color in ceramics, glazes and glass. Cobalt was first isolated in 1735 by a Swedish chemist named Georg Brandt.
    Alloyed Metals The substance is used in corrosion and wear resistant alloys, high speed steels, superalloys, diamond tools and hard metals.
    Pigment Cobalt has been used as a paint and pigment for centuries, as early as the third millenium BC.
    Magnetism Cobalt is used in magnets and magnetic recording media. Cobalt is used in Alnico alloys which make a strong permanent magnet. It is also used in Samarium-cobalt magnets, which are very strong but can be brittle.
    Electroplating Cobalt's appearance, resistance to oxidation and hardness make it a good candidate for electroplating.
