Cobat is a hard, lustrous, silver-gray metal which is used mostly in the production of magnetic, wear-resistant, and high-strength alloys.
Cobalt-based superalloys consume most of the produced cobalt. The temperature stability of these alloys makes them suitable for use in turbine blades for gas turbines and jet aircraft engines, though nickel-based single crystal alloys surpass them in this regard.
Cobalt-based alloys are also corrosion and wear-resistant and therefore are used as well for dental prosthetics, where they are useful to avoid allergies. Some high speed steels also use cobalt to increase heat and wear-resistance. The special alloys of aluminium, nickel, cobalt and iron, known as Alnico, and of samarium and cobalt (samarium-cobalt magnet) are used in permanent magnets. Lithium cobalt oxide (LiCoO2) is widely used in lithium ion battery cathodes.
Cobalt is available in the form of Ingots, flakes, powder and cut/broken cathodes.
