NdFeB Magnets Basic Knowledge And Application

  NdFeB magnets basic knowledge and application

  NdFeB magnets, which is currently found in the highest commercial performance of the magnet, known as the magnetic king, with a small size, light weight and strong magnetic characteristics, is by far the best cost performance of the magnet. Has a very high magnetic properties of its maximum magnetic energy product (BHmax) higher than ferrite (Ferrite) more than 10 times. Its own mechanical processing performance is also quite good. Operating temperature up to 200 degrees Celsius. And its texture is hard, stable performance, a very good price, so its application is extremely extensive. But because of its strong chemical activity, it must be its surface coating treatment. (Such as plating Zn, Ni, electrophoresis, passivation, etc.).

  NdFeB magnets basic knowledge

  NdFeB magnets can be divided into two kinds of bonded NdFeB and sintered NdFeB.

  It is expected that in the next 20 to 30 years, there can be no substitute NdFeB magnets of magnetic materials appear. The main raw materials for the production of NdFeB magnets are metal neodymium, pure iron, boron iron alloy and other additives.

  NdFeB magnets industry's core technology is mainly reflected in the manufacturing process, embodied in its product uniformity, consistency, processing quality, coating quality and so on.

  NdFeB magnet as the third generation of rare earth permanent magnetic materials, has a high cost performance, its widely used in energy, transportation, machinery, medical, IT, home appliances and other industries, especially with the information technology as the representative of the knowledge economy The development of rare earth permanent magnet NdFeB industry and other functional materials continue to bring new uses, which for the NdFeB industry to bring a broader market prospects.

  NdFeB magnets in medical applications:

  NdFeB permanent magnet is the national 863 project project high-tech materials. He can produce is a simulated magnetic field characteristics of the magnetic field, stable performance! The role of the human body can correct the magnetic field of the human body itself, and by enhancing the human body meridian bio-electromagnetic energy, to promote the gas running, so as to achieve through the meridians, increase blood supply to the brain, reduce the cerebral cortex peripheral nerve excitability, Joint tissue metabolism, hypnosis, analgesia, sedation, blood circulation and the effect of eliminating anxiety. Currently used to treat insomnia, neurasthenia, cervical spondylosis, frozen shoulder and other chronic diseases, and these diseases caused by pain, numbness and other symptoms.

  NdFeB magnets are as follows:

  Electroacoustic field: speakers, receiver, microphone, alarm, stage sound, car audio and so on.

  Electronic appliances: permanent magnet mechanism vacuum circuit breakers, magnetic holding relays, watt-hour meter, water meter, sound device, reed switch, sensors and so on.

  Motor field: VCM, CDDVD-ROM, generator, motor, servo motor, micro-motor, motor, vibration motor.

  Machinery and equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery.

  Health care: nuclear magnetic resonance instrument, medical equipment, magnetic health care products, magnetization fuel economy, and so on.

  Other industries: magnetic anti-wax, pipe cleaning, magnetic fixture, automatic mahjong machine, magnetic locks, doors and windows magnetic, luggage magnetic, leather magnetic, toys magnetic, magnetic tools, gifts and other gifts.
