The physical and chemical properties of cobalt determine that it is an important raw material for the production of heat-resistant alloys, cemented carbides, anti-corrosion alloys, magnetic alloys and various cobalt salts. Cobalt-based alloys or cobalt-containing alloy steels are used as gas turbine blades, impellers, conduits, jet engines, rocket engines, missile components and various high-load heat-resistant components in chemical equipment and important metal materials in the atomic energy industry. Cobalt as a binder in powder metallurgy can ensure a certain toughness of cemented carbide. Magnetic alloys are indispensable materials in modern electronics and electromechanical industries, and are used to manufacture various components of sound, light, electricity and magnetism. Cobalt is also an important component of long-lasting magnetic alloys. In the chemical industry, in addition to high temperature alloys and anti-corrosion alloys, cobalt is also used in colored glass, pigments, enamels, catalysts, and desiccants. According to the British "Metal Bulletin" report, the recent strong demand for cobalt from the hard metal sector and super alloys. In addition, cobalt has the highest consumption growth rate in the battery sector. According to relevant domestic reports, the application of cobalt in the battery industry, diamond tool industry and catalyst industry will also be further expanded, so that the demand for metal cobalt is on the rise.
