Cobalt is used
in making batteries,
in electroplating to give a hard surface which is resistant to oxidation,
to give a blue colour in pottery enamels and glass,
is used in Alnico alloy, a material with high magnetic strength,
in Stellite alloy for high speed cutting tools, and
in animal medicine to correct for deficiency in soils.
Cobalt-60, a radioactive isotope is used as a gamma ray source (for use say, in the treatment of cancer, etc.)

Thermally resistant alloys, called superalloys, containing cobalt are used in industry and aircraft gas turbine engines.
An alloy with steel known as cobalt steel is used for making permanent magnets.
With tungsten carbide, cobalt forms Carboloy, a hard material used for cutting and machining steel; alloyed with chromium, cobalt produces Stellite, used for the same purpose.
Cobalt is also used in ceramics and paint driers, and as a catalyst.
