Sc2AlOs
metal· JVASP-41896· Sc2AlOs
Sc2AlOs is an intermetallic compound combining scandium, aluminum, and oxygen, belonging to the family of lightweight metallic oxides and intermetallics. This material exists primarily in research and development contexts rather than as an established commercial product, with potential applications in high-temperature aerospace and structural applications where the combination of low density with reasonable stiffness offers advantages over conventional alloys. Its research interest stems from scandium's role in enhancing aluminum alloys' strength-to-weight ratios and thermal stability, though limited scandium availability and processing complexity currently restrict broader industrial adoption.

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.
