Neodymium magnet, also known as neodymium magnet, is a general term for powerful magnets, and its chemical formula is Nd2Fe 14B. According to NdFeB recycling experts, Nd magnet is the artificial permanent magnet with the strongest magnetic force so far.
At present, the magnet with the highest commercial performance is called Magnetron, which has extremely high magnetic properties, and its maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite.
Neodymium magnet is a tetragonal crystal (Nd2Fe 14B) composed of neodymium, iron and boron. It is predicted that in the next 20 years, there will be no magnetic materials to replace neodymium magnets. The main raw materials for producing neodymium magnets are rare earth metal neodymium, rare earth metal praseodymium, pure iron, aluminum, ferroboron and other rare earth materials.
The application scope of neodymium magnet is as follows:
Electroacoustic field: speakers, receivers, microphones, alarms, stage stereos, car stereos, etc.
Electronic appliances: vacuum circuit breaker with permanent magnet mechanism, magnetic latching relay, watt-hour meter, water meter, sound counter, reed switch, sensor, etc.
Motor field: VCM, CD DVD-ROM, generator, motor, servo motor, micromotor, motor, vibration motor, etc.
Mechanical equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery, etc.
Medical care: magnetic vibrator, medical equipment, magnetotherapy health care products, magnetized oil economizer, etc.
Other industries: magnetized wax remover, pipeline cleaner, magnetic fixture, automatic mahjong machine, magnetic lock, door and window magnets, stationery magnets, luggage magnets, leather magnets, toy magnets, tool magnets, arts and crafts gift packaging, etc.
