Hot pressed Neodymium magnet can fulfill the performance gap between bonded Neodymium magnet and sintered Neodymium magnet. Hot pressed Neodymium magnets are an ideal solution to manufacture radially oriented ring magnet. It still offers the strongest magnetic power nowadays and occupies an absolute predominance in the market share. Sintered Neodymium magnets are produced by conventional powder metallurgy process.
Their overlapped application scope is less and under a complementary relationship. Sintered, hot pressed, and bonded form each has their distinctive magnetic performance. Neodymium magnets can be divided into sintered Neodymium magnets, hot pressed Neodymium magnets, and bonded Neodymium magnets base on the manufacturing process. Since then, Neodymium magnets are served for nearly all industries. The successful development of Neodymium magnet declared the birth of the third-generation rare earth permanent magnet. In addition, Neodymium resource is comparatively rich. Neodymium magnets are primary made from an alloy of Neodymium (Nd), Iron (Fe), and Boron (B) to form the Nd 2Fe 14B main phase which has excellent magnetic properties. It was discovered independently by General Motors and Sumitomo Special Metals in 1984 as they investigated substitutes to the expensive Samarium Cobalt magnet. Neodymium magnet, also referred as NdFeB magnet or Neo magnet, is the most powerful and commonly used rare earth magnet.
