Magnet grade properties

Room-temperature (20 °C) magnetic properties for three permanent magnet families: sintered NdFeB (GB/T 13560-2017), samarium-cobalt SmCo (ZJMAG performance table), and ferrite (DMEGC / GB/T 12796). Values are standard minimums or typical supplier ranges. How to read a grade name →
