These magnets bear a comparatively high energy product and extremely low temperature coefficient, its highest working temperature would extend up to 300°C and no lowest temperature is confined. On the working condition of 180°C, the maximum energy product and stability of temperature about SmCo magnets are all superior to NdFeB magnets.
