Neodymium magnet, also known as NdFeB magnets, is a general term for strong magnets. Its chemical formula is Nd2Fe14B. It is an artificial permanent magnet with the strongest magnetic force at room temperature so far.
NdFeB magnets are widely used. In the field of electroacoustics, it is used for loudspeakers, receivers, microphones, alarms, stage audio, car audio, etc. In the field of electronics and electrical appliances, it is used for permanent magnet vacuum circuit breaker, magnetic retaining relay, watt-hour meter, water meter, microphone, reed, sensor and so on. Motor field: VCM, CDDVD-ROM, generator, motor, servo motor, micro motor, motor, vibration motor, etc. Mechanical equipment: magnetic separation, magnetic separator, magnetic suspension, magnetic machinery, etc. Medical care: nuclear magnetic resonance instrument, medical equipment, magnetic health care products, magnetized fuel saver, etc.
In addition to the mechanical and electrical industry, in other industries, it is mainly used for magnetized wax preventer, pipe descaling device, magnetic fixture, automatic mahjong machine, magnetic locks, door and window magnets, stationery magnets, box and bag magnets, leather magnets, toy magnets, tool magnets, gift packaging, etc.
Because the main raw material of NdFeB magnets
is very cheap, the reserves of rare earth neodymium are more than that of samarium. NdFeB magnets have better mechanical properties than samarium-cobalt magnets and aluminum-nickel-cobalt magnets and are easier to cut, drill and process complex shapes.
