Symposium Magnetics and the Critical Materials Challenge: An FMD Symposium Honoring Matthew J. Kramer
Presentation Title Iron Nitride: a Non-rare-earth Containing Permanent Magnet
Author(s) Frank Johnson
On-Site Speaker (Planned) Frank Johnson
Abstract Scope Niron Magnetics, Inc. is commercializing Iron Nitride, a high performance, completely rare earth free permanent magnet technology. Iron Nitride will act as an economical substitute for several grades of both sintered and bonded NdFeB magnets. Niron’s Iron Nitride technology is based on progress achieved by the University of Minnesota under work supported by the Department of Energy’s Rare Earth Alternatives in Critical Technologies ARPA-E REACT program. These magnets are based on the α”-Fe16N2 compound which has high saturation magnetization and a moderate magnetocrystalline anisotropy due to a tetragonal crystal structure. Iron Nitride is manufactured from low-cost, non-critical elemental components. The unique characteristics of Iron Nitride include a magnetic strength higher than most grades of NdFeB permanent magnets. Test data also indicates that iron nitride exhibits superior temperature stability when compared to NdFeB. Niron’s magnets are positioned to substitute for NdFeB in applications such as motors with high torque output.
