Product introduction
SmFeN magnetic material uses abundant rare-earth Sm element instead of expensive elements of Nd, Dy, Co, etc, and is the most cost-effective rare earth permanent magnetic material. Compared with the bonded neodymium magnet, the bonded SmFeN magnet has higher magnetic properties and lower prices. Moreover, curie temperature, corrosion resistance, and thermal stability of bonded SmFeN magnet perform much better than bonded neodymium magnet. Bonded SmFeN magnet as an alternative of bonded neodymium magnet has broad application prospects.Main applications:Magnetic glass; motor rotor; magnetic ring; etc.
