What is NdFeB?

NdFeB is a tetragonal crystal composed of neodymium, iron, and boron (Nd2Fe14B).

In 1982, Masato Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product (BHmax) of this magnet is larger than that of the samarium cobalt magnet, and it was the substance 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 spray smelting method to prepare NdFeB magnets.

This kind of magnet is a permanent magnet that is second only to the absolute zero holmium magnet in magnetism today, 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, headphones, and battery-powered tools.

Applications of NdFeB:

Sintered NdFeB permanent magnet materials have excellent magnetic properties and are widely used in electronics, motors, medical equipment, toys, packaging, hardware machinery, Aerospace and other fields. More common are permanent magnet motors, speakers, magnetic separators, computer disk drives, magnetic resonance imaging equipment and instruments.

The non-coating treatment of nanometer (Royce3010) chelate film can meet the requirements of 20-30 years of use in marine climate conditions, and can be widely used in sea-based wind power generation. The surface adhesion force is above 20Mpa, and can be widely used in permanent magnet high-speed motors. , special motors, electric vehicle motors, UHV, high-voltage DC power supply systems, fast charging systems, aerospace and military industries and other fields.
