· JVASP-81511· Sc2InAu

Sc₂InAu is an intermetallic compound combining scandium, indium, and gold—a ternary metallic system that exists primarily in the research and development space rather than established industrial production. This material belongs to the family of lightweight intermetallics and precious-metal compounds, which are investigated for specialized applications requiring combinations of low density, thermal stability, and corrosion resistance. Intermetallics like Sc₂InAu are of interest in aerospace, electronics, and high-temperature applications where conventional alloys reach performance limits, though commercial adoption remains limited due to brittleness, processing complexity, and cost constraints typical of multi-component precious-metal systems.

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.
