What is Cobalt?
|Burnished Cobalt Metal in the Drums
Cobalt is a hard ferromagnetic metallic element discovered by a Swedish chemist,
Georg Brandt, in 1739.
It is usually recovered as a by-product of mining/refining nickel, silver, lead, copper and iron.
Cobalt is resistant to stress and corrosion at high temperatures and is used in the following ways:
- In the production of super alloys for the aerospace industry and industrial gas turbines
- In the production of hard metals such as cemented carbides and diamond tooling for metal cutting
- As a pigment in commercial and industrial ceramics and glass, inks, plastics and paints
- In the production of magnets, chemicals and rechargeable batteries
