Samarium Iron Nitride – the next big thing in magnets

Neodymium (Nd) has been the primary source for most commercial rare earth magnets. However, for years the price of Nd has fluctuated greatly and presents a great supply chain risk. However, as a rare earth material, Samarium is much more stable and can dramatically reduce procurement risks. Nichia plans to speak to the benefits specific to Samarium Iron Nitride (SmFeN) as a new bonded magnet material which does not contain Nd, Tb, Dy or Co. Advantages of this new highly spherical magnetic powder include oxidation-resistance, high heat, water and rust resistance. Additionally, as it is capable of injection molding, waste materials are recyclable. Nichia will address specific comparisons to the currently used Nd bonded and sintered magnets through various case studies.
