Cobalt alloys are used mainly in production of chemicals (58 percent), super alloys for gas turbine blades and jet aircraft engines, special steel, carbides, diamond tools and magnets.It is a hard ferromagnetic, silver-white, lustrous, brittle element. It is stable in air and does not react with water. Like other metals, it can also be magnetized. With dilute acids, it reacts slowly.

KEY FEATURES
- Cobalt, like iron, can be magnetised and so is used to make magnets. It is alloyed with aluminium and nickel to make particularly powerful magnets.
- Other alloys of cobalt are used in jet turbines and gas turbine generators, where high-temperature strength is important.
- Cobalt metal is sometimes used in electroplating because of its attractive appearance, hardness and resistance to corrosion.
