Hard magnetic composite materials Nd-Fe-B with additions of iron and X2CrNiMo-17-12-2 steel

Results of polymer matrix hard magnetic composite materials with particles of powdered rapid quenched Nd-Fe-B strip are presented in this paper. Influence of additional materials on magnetic, mechanical and electrical properties of composite materials was studied. The composite without additions revealed good magnetic properties. With addition of soft magnetic materials—iron, the coercive force decreased while remanence of composite was almost not influenced. The addition of steel reduces both coercive force and remanence. However addition of metallic powders improves mechanical properties of the composite materials.
