NdFeB rare earth magnet The third generation of rare earth permanent magnet NdFeB (NdFeB) is the most powerful permanent magnets in the contemporary magnet. As one of the most important application fields of rare earth materials, it is one of the important basic materials supporting the modern electronic information industry and is closely related to people's life. NdFeB is the most powerful and cost-effective permanent magnet material in the modern era. It not only has the features of high remanence, high coercivity, high magnetic energy product and high performance-price ratio, but also can be easily processed into various sizes. Therefore, NdFeB is widely used in aerospace, aerospace, electronics, electro-acoustic, electromechanical, instrumentation, instrumentation, medical technology, magnetic resonance imaging apparatus, magnetic levitation and magnetic seals and other devices and devices requiring permanent magnetic field; Development of high-performance, small, light of the various replacement products.
