Application of Cobalt nanoparticles

1. 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, ducts, jet engines, rocket engine parts, and various high-load heat-resistant parts in chemical equipment and important metal materials in the atomic energy industry. As a binder in powder metallurgy, cobalt can ensure the toughness of cemented carbide. Magnetic alloy is an indispensable material in modern electronics and electromechanical industries, used to make various components of sound, light, electricity and magnetism. Cobalt is also an important component of magnetic alloys. In the chemical industry, in addition to high-alloy and anti-corrosion alloys, cobalt is also used in colored glass, pigments, enamels, catalysts, desiccants, etc.;

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

3. Magnetic fluid
The magnetic fluid produced with iron, cobalt, nickel and their alloy powders has excellent performance and can be widely used in sealing and shock absorption, medical equipment, sound adjustment, light display, etc.;

4. Absorbing materials
Metal nano powder has a special absorption effect on electromagnetic waves. Iron, cobalt, zinc oxide powder and carbon-coated metal powder can be used as high-performance millimeter-wave invisible materials for military use, visible light-infrared invisible materials and structural invisible materials, and mobile phone radiation shielding materials;

5. Micro-nano cobalt powder is used for metallurgical products such as cemented carbide, diamond tools, high-temperature alloys, magnetic materials, and chemical products such as rechargeable batteries, rocket fuel and medicine.
