Sc2TcAu
metal· JVASP-41886· Sc2TcAu
Sc2TcAu is a ternary intermetallic compound combining scandium, technetium, and gold, representing a specialized research alloy rather than a widely commercialized engineering material. This material family sits at the intersection of refractory metallurgy and precious metal chemistry, offering potential in high-performance applications where corrosion resistance, thermal stability, and mechanical strength must be balanced with cost and scarcity constraints. Engineers would consider such materials only in niche, high-value sectors where conventional alternatives cannot meet extreme service conditions, though industrial adoption remains limited due to technetium's radioactivity and extreme rarity.

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.
