Explanation
It is a permanent magnetic material based on intermetallic compounds formed by rare earth metals and transition metals. It is now divided into the first generation (RECo5), the second generation (RE2TM17) and the third generation the rare earth permanent magnetic material (NdFeB). New rare earth transition metal system and rare earth iron nitrogen system permanent magnet alloy materials are being developed, which may become a new generation of rare earth permanent magnet alloy.
