Solid magnetic material is made of rare earth elements (mainly Sm and Er) combined with cobalt, is a permanent magnet with strong magnetic field. Similarly, the heat-resistant alloy, super corrosion resistant cemented carbide also has added cobalt. In many cases, the cobalt is usually used in electroplating, because the weak acid resistance of cobalt plating is much more stable than chromium, nickel plating. Cobalt-based alloys are the generic terms of those alloys that made of cobalt and one or more of the group of chromium, tungsten, iron, nickel. Shear-steel contains certain amount of cobalt can be remarkably improved the steel's wear resistance and machinability. stellite alloy contains more than 50% of cobalt would not lose its original hardness even heated to 1000?, now this cemented carbide has become the most important materials of gold-containing cutting tools and aluminum used. In this material, cobalt hangs together other metal carbide grains of the alloy, the alloy with higher toughness, reduce the sensitivity to shocks, this alloy welding on the surface of the part, can increase 3-7 times of the parts life. Cobalt oxide is mainly used for the production of cemented carbide and ceramic enamel color. Cobalt sulfate is mainly used for ceramics, color glaze, paint driers and electroplating industries. Cobalt chloride is mainly used for manufacturing barometer, hydrometer and ceramics. Naphthoic acid cobalt salts are mainly used in paints and inks' driers, colorants, rubber tackifier and FRP industry. Cobalt iso-octoate mainly used in the paint, glass steel and rubber radial tires and so on. The biggest application field of cobalt is secondary battery. The reason why cobalt has a larger increase in the battery field application is primarily the result of the development of lithium-ion batteries. In today's world information and communication industry, as well as environmental protection and energy conservation field, lithium ion batteries are the latest generation of batteries, its specific energy, charging and discharging cycle life is higher than nickel batteries. Cobaltous oxide is used in nickel-metal hydride batteries. Because of the excellent properties of cobalt, it is difficult to be replaced by other metals in the manufacture of high temperature resistant, corrosion-resistant alloys, therefore, the application of cobalt in superalloys field is still very strong, superalloy is currently the second largest application areas of cobalt. Cobalt has good wettability with many metals at high temperatures, low temperatures, so that cobalt powder is widely used as adhesives, almost to be irreplaceable carcass binder of diamond tools, carbide. Chinese production of cemented carbide ranks first in the world, the production of diamond tools also ranks highest in the world. Cobalt-based alloy powder is widely used in thermal spraying, for internal combustion engines exhaust valve sealing surface, valve seats, large bearing's inner and outer ring, large turbine rotor blades, spray welding of oil press propellers. For a variety of propeller parts, secret training machine parts, spray welding of pump leaves. Magnetic material is an important functional material, plays a very important role in the electronics industry and other high-tech areas. Cobalt's magnetic materials field application distribute as follows: 70% for permanent magnet alloys, 20% for magnetic alloys, 10% for the other rare earth permanent magnet materials. Cobalt catalyst is mainly used for the production of polyester fiber materials. Cobalt titanate is the main oil desulfurization catalyst. Purity cobalt target is used for the process of semiconductor physical vapor deposition. Metal powder suppliers predicted that the application of cobalt in the battery industry, diamond tools industry and the catalyst industry will be further expanded, thus the market demand for the metal cobalt is showing an upward trend.
