· Mg1 Sc2 Al1

Mg1Sc2Al1 is an experimental magnesium-scandium-aluminum intermetallic compound classified as a semiconductor, representing a niche composition within the lightweight magnesium alloy family. This ternary system combines the low density and corrosion resistance benefits of magnesium with scandium's strengthening and recrystallization-control properties, along with aluminum's solid-solution hardening effects—a combination primarily explored in research contexts rather than established industrial production. The semiconducting character suggests potential applications in thermoelectric or electronic device contexts where the material's unique electronic properties could be leveraged, though such applications remain largely experimental and would require validation of processing routes and reproducibility.

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.
