What standard can be called high performance NdFeB

High-performance NdFeB criteria: Hcj(kOe) (BH)max(MGOe)> >60. At present, according to the regulations of "China High-tech Products Catalogue (2006)", it is made by quick-setting belt throwing method. The sum of intrinsic coercivity Hcj(kOe) and maximum magnetic energy ((BH)max,MGOe) is greater than 60. It is used to make sintered NdFeB permanent magnet materials for medium, small and micro special purpose permanent magnet motors, sensors, magnetic resonance instruments, advanced audio equ
