These magnets are obtained from shape moulds compression of NdFeB "rapid quenched" (patented MQP) and thermohardening resin. The grains dimension enables to obtain good end-precision without needing further mechanical processing. Very good sensibility as regards both flux density and coercive field. Typical protective coatings in epoxidic resin. |
