· JVASP-148161· U3Sn4Au3

U3Sn4Au3 is an intermetallic compound combining uranium, tin, and gold—a ternary metal system of primarily academic and materials research interest rather than established industrial production. This material belongs to the family of uranium-based intermetallics, which are studied for understanding phase relationships, crystallographic structure, and potential applications in specialized high-density or high-temperature contexts. The addition of gold to uranium-tin systems is uncommon in practice; this composition appears in phase diagram research and fundamental metallurgy rather than in mainstream engineering applications.

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.
