· ScSnAu

ScSnAu is a ternary intermetallic compound combining scandium, tin, and gold—a research-phase alloy belonging to the family of rare-earth and precious-metal intermetallics. This material is not yet established in mainstream engineering practice but represents an experimental composition of interest in materials science for exploring novel mechanical and physical properties that may arise from the combination of a light refractory metal (Sc), a common tin-based intermetallic former (Sn), and a noble metal (Au). Such ternary systems are typically investigated for fundamental studies of elastic behavior, phase stability, and potential applications in high-performance or specialized environments where conventional alloys fall short.

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.
