SmFeN Magnet
Sm-Fe-N magnet powders are produced in a similar way to Nd-Fe-B, except that nitrogen is introduced by heat treatment of rapidly quenched Sm-Fe flakes in a nitrogen atmosphere. These flakes are then mixed with a polymer binder and pressed or injected to make isotropic bonded magnets, NITROQUENCH-P.
Magnetic performance of (BH)max=112 kJ/m3 is at the highest level in the world and has excellent corrosion and heat resistance, which opens the door to various new applications.
