· DyFeSi

DyFeSi is an intermetallic compound combining dysprosium (a rare-earth element), iron, and silicon. This material is primarily of research and specialized industrial interest, valued for its magnetic and thermal properties that emerge from rare-earth–transition metal interactions. Applications span magnetic refrigeration systems, permanent magnet technologies, and high-temperature structural applications where rare-earth strengthening is beneficial, though it remains less common than established alternatives like Nd–Fe–B magnets or conventional steels in mainstream engineering.

Export Control

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.
