Rare earth cobalt hard magnetic alloy
Rare earth cobalt hard magnetic alloy is one of the most important magnets in practical applications. It is composed of two elements cobalt and rare earths, mainly samarium, neodymium and dysprosium. It has excellent magnetic properties and has become an important material commonly used in industrial production, aviation, navigation and other fields.
At present, the production of rare earth cobalt hard magnetic alloy mainly adopts the powder metallurgy technology. It is mainly composed of large grain, small grain and fine powder. The main purpose of this alloy is to reduce its coercive force and improve the saturation magnetic induction strength. Moreover, it is also characterized by high Curie temperature and temperature resistance, which makes it widely used in special motor, magnet electric pump, magnetic communication devices and other occasions.
In terms of the rare earth cobalt hard magnetic alloy production process, it has the advantages of high efficiency, low cost and good homogenization. Generally, the production process mainly includes processes such as powder preparation, powder pressing, sintering, magnetic and heat treatment. The common shape of the product is ring, array and disc, as well as non-standard shape customization ability for customers.
In addition to its excellent magnetic properties, the rare earth cobalt hard magnetic alloy also has the advantages of small volume, strong corrosion resistance, light weight and shock resistance. Its excellent mechanical and chemical properties make it particularly suitable for motors, electronics, microphones, micro-motors, magnetic relays, magnetic valves, electronic instrumentation, magnetic bearings and other industries.
In summary, rare earth cobalt hard magnetic alloy is one of the most important magnets in practical use, and its excellent magnetic properties, small volume, high efficiency, low cost and good homogenization make it wide applications in many fields. With the further development of rare earth industry, rare earth cobalt strong magnetic alloy will be increasingly widely used in different industries, and its application and development prospects can be expected.
