NdFeB magnets are a mixture of barium, iron, boron, antimony, cobalt and other trace elements. As the third-generation rare earth permanent magnet, NdFeB magnets have become the most popular commercial permanent magnet materials. NdFeB has sintered and bonded two forms. Sintered NdFeB has very high magnetic properties, excellent magnetic properties and good performance in high temperature environments. The mechanical strength of NdFeB is superior to that of samarium cobalt, and is not as brittle as ceramic and yttrium-nickel-cobalt magnets. However, NdFeB magnets are very susceptible to corrosion. Therefore, if used for a long time, special coatings such as zinc, nickel, nickel-copper-nickel, or epoxy must be applied to their surfaces.
Sintered NdFeB magnets need to be refined to achieve the final tolerances. We use the latest equipment and technology to produce the world’s highest energy magnets for use in applications such as magnetic resonance (MRI) and voice coil motors (VCM) and other applications with energy-efficient raw materials. With high coercivity, Weijin serves the market with high performance motors, generators, sensors and other applications used materials. Our NdFeB magnets are extremely cost effective. The magnets are small in shape and size, but they contain high magnetic properties. In addition, our low manufacturing costs will significantly reduce your application costs.
Application: NdFeB magnets are widely used in machinery, video, audio drive technology, communication equipment, medical equipment, office automation equipment, aerospace and so on.
Weijin's magnets are mainly used in motors and generators, such as: elevator motors (traction machines), wind power generation, servo motors, motors for hybrid electric vehicles and battery electric vehicles, linear motors, air compressor motors, etc.
