SmDyFe17
metal· JVASP-121585· SmDyFe17
SmDyFe17 is a rare-earth iron-based intermetallic compound combining samarium and dysprosium with iron in a fixed stoichiometric ratio. This material belongs to the family of rare-earth permanent magnets and hard magnetic phases, engineered to achieve high magnetic coercivity and saturation magnetization through rare-earth substitution. It is primarily investigated for high-temperature magnetic applications where superior thermal stability and coercive strength are required beyond conventional ferrite or alnico magnets, though it remains largely in the research and development phase rather than commodity production.

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.
