ORDER FORM

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.

ALUMINUM POWDER APPLICATIONS:
Cobalt is a ferromagnetic metal that is silver or gray. Compounds of cobalt occur naturally, however pure cobalt is not found in nature. It scores a 5.5 on the Mohs scale of mineral hardness. Some of the major applications include:

Alloyed Metals
The substance is used in corrosion and wear resistant alloys, high speed steels, superalloys, diamond tools and hard metals.

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.

Pigments
Cobalt has been used as a paint and pigment for centuries, as early as the third millenium BC.
