· JVASP-56971· DyFe5

DyFe5 is an intermetallic compound composed of dysprosium and iron, belonging to the rare-earth iron family of magnetic materials. It is primarily investigated for high-temperature permanent magnet applications where superior magnetic properties and thermal stability are required compared to conventional ferrite or alnico magnets. DyFe5 is notable in the rare-earth magnet family for its potential to replace or augment neodymium-based magnets in specialized aerospace, automotive, and energy applications where operating temperatures exceed the practical limits of standard NdFeB systems.

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.
