NdFeB magnets range of applications as follows

May 12, 2023

Acoustic field: the speaker, receiver, microphone, alarm, stage audio, car audio.
Electronic appliances: permanent magnetic actuator vacuum circuit breakers, magnetic relays, meter, water meter, sound meter, dry reed pipe, sensors.
Motor areas: VCM, CDDVD-ROM, generators, motors, servo motors, micro-motors, motors, vibration motors.
Machinery and equipment: magnetic separation, magnetic separation machine, magnetic crane, magnetic machinery.
Healthcare: MRI scanners, medical equipment, magnetic health products, magnetic fuel economy and the like.
Other industries: magnetized wax, pipe descaling, magnetic fixture, automatic mahjong machine, magnetic locks, doors and windows magnetic stationery magnetic, magnetic bags, leather magnetic toys magnetic, tools magnetic, craft gift packaging.
The third generation of rare earth permanent magnet NdFeB is the strongest performance of contemporary permanent magnets. Its value is 5-12 times BHmax ferrite magnets, is 3-10 times alnico magnet; it's the equivalent of 5-10 times the coercive force of ferrite magnets, alnico magnet 5 15 times, its magnetic potential is extremely high, it can pick up the equivalent of 640 times the weight of its own weight.
As the main raw material of iron NdFeB magnets are very cheap, compared with reserves of rare earth neodymium, samarium more than 10-16 times, so the price is much lower than the samarium-cobalt magnets.
Mechanical properties of NdFeB magnets are better than samarium cobalt magnets and alnico magnets, easier cutting and drilling and machining complex shapes.
Deficiencies NdFeB magnet is its poor temperature performance, high temperature magnetic loss is large, the maximum operating temperature is lower. Generally around 80 degrees Celsius, after special treatment magnet, its maximum operating temperature up to 200 degrees Celsius.
Because the material contains large amounts of neodymium and iron, it is easy to corrosion is one of its major weaknesses. So NdFeB magnets have the surface coating. Nickel can be electroplated (Ni), zinc (Zn), gold (Au), chromium (Cr), epoxy resin (Epoxy) and the like.
NdFeB magnets are widely used in aerospace, electronics, electrical, instrumentation, medical and other fields. And the use of non-technical areas are increasingly being used, such as adsorption magnets, toys, jewelry and the like.
