· JVASP-99993· DyYFe4

DyYFe4 is an intermetallic compound combining dysprosium, yttrium, and iron, belonging to the rare-earth iron family of magnetic materials. This material is primarily investigated for permanent magnet and magnetostrictive applications where high-performance magnetic properties and thermal stability are critical, particularly in specialized actuators, sensors, and high-temperature magnetic devices where conventional rare-earth magnets reach their limits.

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.
