Cobalt powder is gray and irregular, soluble in acid, magnetic, easy to oxidize in wet air. It is widely used in aviation, aerospace, electrical, mechanical manufacturing, chemical and ceramic industries. Cobalt based alloys or cobalt containing alloy steels are used as high temperature heat-resistant parts and important metal materials in atomic energy industry as blades, impeller, conduit, jet engine, rocket engine, missile component and chemical equipment of turbine. As a binder in powder metallurgy, cobalt can ensure the toughness of the hard alloy. Magnetic alloys are indispensable materials in modern electronics and mechanical and electrical industries, which are used to make various components of sound, light, electricity and magnetic materials. Cobalt is also an important part of permanent magnetic alloys. In chemical industry, cobalt isused in high alloy and anticorrosive alloy, and also used in colored glass, pigment, enamel, catalyst and desiccant. Application -Water atomized cobalt powder has a relatively coarse grain size, which can be used in welding materials to improve its toughness, impact resistance and wear resistance. -Reduced cobalt powder is in fine size and high purity, can be widely used in diamond tools, powder metallurgy,
