A real super magnet, what is Neodymium magnet?
Neodymium magnet is also called neodymium iron boron magnet. It is a permanent magnet with a Nd2Fe14B tetragonal crystal structure, composed of alloys of neodymium, iron, and boron. Its main components are rare earth elements neodymium (Nd), iron (Fe), and boron (B). Neodymium is a part of this material, known as "rare earth". Rare earths are named not because of their natural concentration, but because of the difficulty of separating them from other materials connected by Chemical bond. Therefore, it can be said that Neodymium magnet are not the cheapest, but their magnetic force is the most powerful, and this greater power can exist in a few centimeters of magnets.
Neodymium magnet has nickel, zinc or copper coating, which has excellent resistance to atmospheric medium. Neodymium magnet is the strongest magnet on the market at present, known as the king of magnets. They have very high magnetic properties, and their maximum energy product (BH) is 10 times greater than that of ferrite magnets. Neodymium iron boron has excellent processing performance, with a working temperature of up to 200 ° C. Moreover, Neodymium magnet has stable performance and good cost performance, so it is widely used in various industries.
What are the applications of Neodymium magnet
Among modern products that need powerful permanent magnets, Neodymium magnet have replaced other types of magnets. The application scope of neodymium iron boron magnets is as follows: 1. Electroacoustic field: speakers, receivers, microphones, alarms, stage audio, car audio, etc. 2. Electronic products: permanent magnet vacuum circuit breaker, magnetic holding relay, Electricity meter, water meter, sound level meter, reed switch, sensor, etc. 3. Motor field: VCM, CDDVD-ROM, generator, motor, servo motor, micro motor, vibration motor, etc. 4. Mechanical equipment: magnetic separator, magnetic separator, magnetic hoist, magnetic machinery, etc. 5. Medical and health care: magnetic resonance imaging machines, medical devices, magnetic therapy health products, magnetized economizers, etc. 6. Other industries: anti magnetic wax, pipeline cleaning agent, fixed magnetic device, automatic mahjong machine, magnetic lock, door and window magnet, stationery magnet, luggage magnet, leather magnet, toy magnet, tool magnet, craft gift packaging, etc.
History of Neodymium magnet
The neodymium iron boron magnet was discovered by Masato Sato of Sumitomo Special Metals Co., Ltd. in 1982. The maximum magnetic energy product (BH) of a magnet is greater than that of a cobalt magnet, which was the material with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed a powder metallurgy method, and General Motors successfully developed a melt spinning process that can prepare neodymium iron boron magnets. Neodymium iron boron magnets are currently the most powerful permanent magnets and the most commonly used rare earth magnets.
