· Al1 Sc1 Au2

Al₁Sc₁Au₂ is an intermetallic compound combining aluminum, scandium, and gold in a defined stoichiometric ratio, classified as a semiconductor. This is a research-phase material rather than a commercial alloy; such ternary intermetallics are studied for potential electronic and optoelectronic applications where the combination of a light metal (Al), a reactive rare earth element (Sc), and a noble metal (Au) may produce tunable band structure or enhanced carrier transport. The material family is of interest in advanced materials research for high-performance semiconductors and possibly thermoelectric or photonic devices, though practical industrial adoption remains limited pending further characterization and scalable synthesis methods.

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.
