Market Use Of Neodymium Sphere Magnets
As the third generation of rare earth permanent magnet, neodymium sphere magnets has high performance. It is widely used in energy, transportation, machinery, medical, IT, household electrical appliances and other industries. n particular, with the development of information technology as the representative of the knowledge-based economy, the rare earth permanent magnet NdFeB industry and other functional materials continue to bring new uses, which will bring more broad market prospects for the NdFeB industry.
Neodymium sphere magnets is a tetragonal crystal formed by neodymium, iron, and boron. In 1982, Sakawa Masahito discovered the neodymium magnet in Sumitomo special metal. The magnetic energy of this magnet is larger than that of samarium cobalt magnet, which is the largest magnetic energy product in the world. Later, a successful powder metallurgy process was developed by the special metal of Sumitomo and the melt-spinning process was successfully developed by general motors, and the NdFeB magnets were prepared. This magnet is the most powerful permanent magnet and the most commonly used rare earth magnet which is widely used in electronic products such as hard disks, mobile phones, headphones, and battery powered tools and so on.
In order to avoid corrosion damage, it is necessary to protect the surface of the neodymium sphere magnet material, such as gold, nickel, zinc, tin plating, and surface spraying epoxy resin. NdFeB is a high-tech material of the National 863 project plan. It belongs to high-end rare earth materials. In terms of medical treatment, NdFeB has been widely used in physical magnetic therapy.
