The trend of the development of ndfeb permanent magnet material _ ndfeb strong magnet manufacturers

by:Newland     2020-04-02
The trend of the development of ndfeb permanent magnet material is as follows: 1, in terms of bonded ndfeb permanent magnet materials, duplex nanometer composite permanent magnetic materials such as rare earth content is low, the comprehensive advantages of magnetic can be good and be future research hot spot and focus; 2, due to the bonded ndfeb has high cost performance, so the other magnetic powder mixed with ndfeb magnetic powder made from multivariate composite bonded magnet is concerned. Complex system are: the rapid quenching ndfeb magnetic powder and magnetic ferrite powder composite, rapid quenching ndfeb magnetic powder and samarium cobalt powder composite, isotropic ndfeb magnetic powder and anisotropic ndfeb magnetic powder in the composite, etc. , it is also one of the important direction of future ndfeb technology; 3, in terms of sintered ndfeb permanent magnet materials, and the future research hot spot and focus is to reduce the content of heavy rare earth metal Dy, Tb; 4, ndfeb permanent magnet material corrosion and protection is still the focus and hotspot in the research of the future technology.
