Cobalt Alloys

الوصف

Cobalt is a hard ferromagnetic, silver-white, hard, lustrous, brittle element. It is a member of group VIII of the periodic table. Like iron, it can be magnetized. It is similar to iron and nickel in its physical properties. The element is active chemically, forming many compounds. Cobalt is stable in air and unaffected by water, but is slowly attacked by dilute acids.

Cobalt is used in many alloys (superalloys for parts in gas turbine aircrafr engines, corrosion resistant alloys, high-speed steels, cemented carbides), in magents and magnetic recording media, as catalysts for the petroleum and chemical industries, as drying agents for paints and inks. Cobalt blue is an important part of artists' palette and is used bu craft workers in porcelain, pottery, stained glass, tiles and enamel jewellery. The radioactive isotopes, cobalt**0, is used in medical treatment and also to irradiate food, in order to preserve the food and protect the consumer.

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.
Cobalt salts have been used for centuries to produce brilliant blue colours in paint, porcelain, glass, pottery and enamels.
Radioactive cobalt**0 is used to treat cancer and, in some countries, to irradiate food to preserve it.
