  International trends of high temperature samarium cobalt magnets

  In the past two years, the price of high temperature samarium cobalt magnets has been rising and rising again. Why do the prices of many magnets such as high temperature resistant samarium cobalt magnets continue to rise instead of falling? In fact, this is mainly because our high temperature resis ...

  The sintering of sintered NdFeB is one of the most important processes

  Sintered NdFeB is an anisotropic magnet produced by powder sintering. Generally, only blanks can be produced after sintering, and then through machining (such as wire cutting, slicing, grinding, etc.), magnets of various shapes can be formed. The sintering of sintered NdFeB means that in order to f ...

  Effective solutions for high temperature demagnetization of NdFeB magnets

  Iron boron, also known as neodymium iron boron magnet (NdFeB magnet), is a tetragonal crystal formed by neodymium, iron, and boron (Nd2Fe14B). Neodymium magnets were discovered in 1982 by Masato Sagawa of Sumitomo Special Metals in Japan. The magnetic energy product (BHmax) of this magnet is greate ...

  NdFeB magnet production–melting

  Sintered NdFeB is a very widely used magnetic material. It is an alloy of neodymium, iron, boron, rare earth and other materials combined. In order to prevent the impact on the basic composition of the magnet, we need to smelt the raw materials. Treatment is performed to avoid the mixing of impurit ...

  magnetron sputtering

  Different from the vapor deposition diffusion method described above, magnetron sputtering separates the Dy deposition process from the diffusion process. It deposits Dy on the surface of the original magnet by physical sputtering, and then performs high temperature diffusion. Magnetron sputtering ...

  Grain Boundary Diffusion Technology

  The traditional method of adding elements is to add them in the smelting process, that is, smelting Dy, Tb, Nd, Fe, B and other elements together, and Dy is distributed in the grain boundary and the main phase of the grain in the produced magnet. However, studies have shown that Dy at the grain bou ...
