· Sc2AlSi2

Sc2AlSi2 is an intermetallic compound combining scandium, aluminum, and silicon, representing a lightweight metallic material from the family of rare-earth containing intermetallics. This compound is primarily of research and development interest rather than established industrial production, with potential applications in aerospace and high-temperature structural components where weight reduction and thermal stability are critical. The scandium additions are known to strengthen aluminum-based systems and improve creep resistance, making this composition relevant to advanced alloy development programs seeking next-generation lightweight materials.

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.
