What is a neodymium magnet?

Date: 2021-04-16 | Category: INDUSTRY NEWS

  Neodymium magnets, also called neodymium iron boron magnets, are tetragonal crystals formed by neodymium, iron, and boron.

 

  In 1982, Masato Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product of this magnet is greater than that of a samarium cobalt magnet, and it was the material with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed the powder metallurgy method, and General Motors successfully developed the rotary jet smelting method, which was able to prepare neodymium iron boron magnets. This kind of magnet is a permanent magnet whose magnetism is second only to that of absolute zero degree holmium magnet, and it is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools.

  In order to avoid corrosion damage, it is necessary to do a protective treatment on the surface of the permanent magnet material during use, such as electroplating with gold, nickel, zinc, and tin, and spraying epoxy resin on the surface.
