Technical characteristics

Cobalt is a brittle, hard metal, similar in appearance to iron and Nickel. Cobalt has a magnetic permeability approximately two thirds lower than iron. It is often produced as a by-product of Nickel, silver, lead, copper and iron ores. Cobalt is often used in alloys with other metals (iron, tungsten, titanium) due to its unusual magnetic strength and is used in the processes of application of electroplating, which are characterized by high hardness and oxidation resistance.

Cobalt rods, and wire used in the manufacture of hard alloys and in batteries. Superalloys consume a higher quantity of cobalt. Temperature stability of these alloys makes them suitable for use in turbine blades for gas turbines and jet aircraft engines. Alloys based on cobalt are also corrosion and wear — resistant.

Other applications of cobalt circle and wire — manufacture of permanent magnets. The lithium oxide-cobalt (LiCoO2) is widely used as electrodes of lithium ion batteries.

Cobalt and its compounds, especially cobalt carboxylates (known as cobalt Soaps) are good oxidation catalysts. They are used in paints, varnishes, and inks as drying agents through the oxidation of certain compounds. They are used to improve the adhesion of steel to rubber in radial tires, steel tape.
