· JVASP-40113· DySnAu2

DySnAu2 is an intermetallic compound combining dysprosium (a rare-earth element), tin, and gold in a fixed stoichiometric ratio. This is a research-phase material rather than a commodity alloy; intermetallics of this type are investigated for specialized applications requiring combinations of thermal stability, electrical conductivity, and mechanical properties not easily achieved in conventional alloys. The dysprosium-tin-gold system belongs to a family of rare-earth intermetallics of interest in materials science, though industrial adoption remains limited and applications are primarily experimental or confined to niche sectors such as thermoelectrics, electronic interconnects, or high-temperature coatings where the unique phase stability and elemental properties justify the cost and processing complexity.

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.
