The application of cobalt powder 

1. High density magnetic recording material can greatly improve the performance of tape and large-capacity hard and soft disks by using the advantages of high recording density, high coercivity (up to 119.4KA/m), high signal-to-noise ratio and good oxidation resistance of nano-cobalt powder;  

2. Magnetic fluid with iron, cobalt, nickel and their alloy powder production of excellent performance, can be widely used in sealing shock absorption, sound regulation, light display, etc;  

3. Metal nano-powder, the absorbing material, has special absorption effect on electromagnetic wave. Iron, cobalt, zinc oxide powder and carbon coated metal powder can be used as military high-performance millimeter wave stealth materials, visible light - infrared stealth materials and structural stealth materials, as well as mobile phone radiation shielding materials;

4. Nano cobalt powder is used as hard alloy, diamond tools, high temperature alloy, magnetic materials and other metallurgical products.

5. Widely used in aviation, aerospace, electrical appliances, machinery manufacturing, chemical and ceramic industries. Cobalt-based alloys or cobalt-containing alloy steels are used as blades, impellers, conduits of steam turbines, parts of jet engines, rocket engines, missiles and various heat-resistant parts with high loads in chemical equipment as well as important metal materials in atomic energy industry. Cobalt as a binder in powder metallurgy can ensure the toughness of cemented carbide. Magnetic alloy is an indispensable material in modern electronics and electromechanical industry. It is used to manufacture various components of acoustic, optical, electric and magnetic equipment. Cobalt is also an important component of magnetic alloys. In chemical industry, cobalt in addition to high alloy and anticorrosive alloy, also used in colored glass, pigment, enamel and catalyst, desiccant, etc.
