Application field1. High-density magnetic recording material utilizes nano-cobalt powder to record high density, high coercivity (up to 119.4KA/m), high signal-to-noise ratio and good oxidation resistance, which can greatly improve tape and large-capacity soft and hard. Disk performance;
2, magnetic fluid with iron, cobalt, nickel and its alloy powder production of magnetic fluid performance is excellent, can be widely used in sealing shock absorption, medical equipment, sound adjustment, light display, etc.;
3. Absorbing material The 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 stealth materials for military use, visible light infrared stealth materials and structural stealth materials, and mobile phone radiation shielding materials;
4. Ultra-fine cobalt powder is used as metallurgical products such as cemented carbide, diamond tools, high-temperature alloys, magnetic materials, and chemical products such as rechargeable batteries, industrial blasting agents, rocket fuels and medicines;
5. Widely used in aviation, aerospace, electrical, mechanical manufacturing, chemical and ceramic industries. Cobalt-based alloys or cobalt-containing alloy steels are used as vane blades, impellers, ducts, jet engines, rocket engines, components of missiles, and various high-load heat-resistant components in chemical equipment and important metal materials for 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 the modern electronics and electromechanical industries for the manufacture of various components of acoustic, optical, electrical and magnetic equipment. Cobalt is also an important part of permanent magnetic alloys. In the chemical industry, in addition to high alloys and anticorrosive alloys, cobalt is also used in colored glass, pigments, ruthenium and catalysts, desiccants and the like.
