Rare Earth Permanent Magnets
NdFeB magnets are a member of rare earth permanent magnets and are the most powerful permanent magnets in the world. Because it is mainly composed of three materials, neodymium (Nd) iron (Fe) and boron (B), it is called neodymium iron boron, also known as neodymium magnet or magnetic steel. NdFeB is the third-generation rare earth permanent magnet, and its excellent magnetic properties and low price make it widely used. It is the rare earth permanent magnet with the highest degree of commercialization at present.
NdFeB grade
N35, N38, N42, N38SH... what does this mean? Neodymium magnets are made of all the materials they make. As a very general rule, the higher the rank, the stronger the magnet. The highest grade neodymium magnets are available N52. Any of the following ratings refer to the temperature rating of the magnet. If there is no grade below the letter, the NdFeB magnet is the standard temperature. High temperature grade standard --M---SH--UH--EH, in NdFeB performance and physical parameters, you can find various temperature grades.
