· JVASP-141278· Sm2Fe17N3

Sm₂Fe₁₇N₃ is a samarium-iron nitride permanent magnet material belonging to the rare-earth intermetallic family, engineered for high-performance magnetic applications. This compound is used in motors, generators, actuators, and magnetic sensors where strong permanent magnetism and thermal stability are required, offering advantages over conventional ferrite magnets in compact designs and performance-critical systems. It represents an important research and development material in the permanent magnet sector, competing with NdFeB and other rare-earth systems for weight-sensitive and high-temperature applications.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
