NdFeB (NdFeB) is a third-generation rare-earth permanent magnet material, with small size, light weight and strong magnetic characteristics, is by far the best performance-price ratio of the magnets, in the field of magnetism known as the king of magnets. The advantages of high energy density make NdFeB permanent magnet materials are widely used in modern industry and electronic technology.
In people's daily life, small to watches, cell phones, cameras, telephones, tape recorders, computer hard drives, CD-ROM drives, large to automobiles, generators, medical instruments, aviation and spacecraft, etc., permanent magnet materials are omnipresent. It is due to the extensive use of rare earth permanent magnetic materials, many electronic products to further reduce the size, performance has improved significantly. Thus adapting to the development trend of today's lightweight, thin and small electronic products. Now, the production and application of rare-earth permanent magnetic materials has become an important symbol to measure a country's comprehensive national strength and the level of national economic development.
