· JVASP-62955· DyFeB4

DyFeB4 is an intermetallic compound combining dysprosium (a rare-earth element), iron, and boron. This material belongs to the family of rare-earth iron borides, which are primarily of research and developmental interest rather than established industrial commodities. DyFeB4 and related rare-earth boride compounds are investigated for potential applications in high-temperature structural materials, magnetic applications, and wear-resistant coatings, leveraging the hardness and thermal stability that boride phases can provide.

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.
