ScAl2Au
metal· JVASP-156150· ScAl2Au
ScAl2Au is an intermetallic compound combining scandium, aluminum, and gold in a defined stoichiometric ratio. This material belongs to the family of rare-earth and precious-metal intermetallics, which are typically explored for specialized high-performance applications where conventional alloys fall short. ScAl2Au remains largely a research-phase material; it is not widely deployed in mainstream industrial production, but intermetallics of this type are investigated for applications demanding exceptional hardness, thermal stability, or corrosion resistance at elevated temperatures.

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.
