Cobalt is a shiny steel-gray metal, hard and brittle, ferromagnetic, when heated to 1150ºC magnetic disappear.Cobalt has two and three valences.It does not interact with water at room temperature and is stable in humid air.When heated in air to more than 300ºC, CoO is oxidized and burned to Co3O4 in white heat.The fine cobalt powder by hydrogen reduction can spontaneously ignite to form cobalt oxide in air.Cobalt is mainly used to make alloys.Cobalt-based alloy is a general term for one or more alloys made of cobalt and groups of chromium, tungsten, iron, and nickel.A certain amount of cobalt in the tool steel can significantly improve the wear resistance and cutting performance of the steel.Stellite hard alloy containing cobalt 50 or more will not lose its original hardness even if heated to 1000ºC. Now this kind of hard alloy has become the most important material used between gold-bearing cutting tools and aluminum.In this material, cobalt combines the carbide grains of the other metals in the alloy composition to make the alloy more ductile and less sensitive to impact. The alloy is welded to the surface of the part and the life of the part is increased by 3-7 times.The most widely used alloys in aerospace technology are nickel-based alloys and cobalt-based alloys can also be used.
