· JVASP-22758· DyAl7Au3

DyAl7Au3 is an intermetallic compound composed of dysprosium, aluminum, and gold, representing a rare-earth metallic system investigated primarily in materials research rather than established industrial production. This compound belongs to the family of rare-earth intermetallics, which are studied for potential applications requiring specific combinations of hardness, thermal stability, and electronic properties that differ significantly from conventional aluminum or gold alloys. Limited commercial deployment exists; the material is notable within the research community for understanding phase stability and properties in ternary rare-earth systems, with potential relevance to specialized high-performance applications where rare-earth strengthening mechanisms could provide advantages over conventional alternatives.

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.
