NdFeB Magnets
| Origin: | China |
|---|
NdFeB Magnet is mainly made of Neodymium, Iron and Boron, with excellent magnetic property, abundant raw material and reasonable prices, NdFeB Magnet can be used as an ideal magnet in mini-motor, permanent magnetic resonance, sound device magnetic suspension system, magnetic transmission machine, iatrical apparatus, etc.
Special Requirements of NdFeB Magnets
Surface Treatment
Painting, coating, or plating is highly recommended for NdFeB. Nickel, Zinc, Tin? ? Phosphor, Silver or Gold Plating, Spray Coating or Epoxy Resin plating provides good corrosion resistance for NdFeB magnets. A variety of organic coatings have been successfully developed for NdFeB, exhibiting good corrosion resistance characteristics.
Machining
In general, NdFeB magnets must be machined using diamond-grinding techniques. Machining this material removes a layer of protective coating, and re-coating for corrosion resistance may be necessary.
Magnetizing and Handling
Rare Earth materials must be handled very carefully to avoid damage and injury. Isotropic bonded NdFeB materials can be magnetized in any direction, or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple pole magnetization.
