Flexible Samarium Iron Nitrogen Motor SmFeN Magnetic Sheet
SmFeN Magnets
SmFeN magnets are anisotropic magnets made of SmFeN magnetic powder and engineering plastic PA12 mixed and granulated, and then injection molded in a directional magnetic field. Its oxidation resistance and corrosion resistance are better than NdFeB, and it is 2~3 times better than similar NdFeB materials. The products are mainly used in sensors, motors, etc.

SmFeN magnet characteristics
The Curie temperature can reach 476 degrees Celsius, which is much
higher than that of conventional sintered Nd magnets.
The magnetic crystal anisotropy field is three times higher than
that of Nd 2 Fe 14 B, offering great potential for high coercivity
magnets.
SmFeN magnets can be magnetically tuned without the addition of
cobalt or other heavy rare earth elements (HREE).
Excellent corrosion and oxidation resistance.
