· JVASP-15700· SrAl2Si2

SrAl2Si2 is an intermetallic compound combining strontium, aluminum, and silicon—a ternary metal system with potential for lightweight structural applications. This material belongs to the family of aluminum-silicon intermetallics and is primarily of research and development interest rather than an established industrial commodity. Researchers investigate such Sr-Al-Si compounds for aerospace and thermal management applications where low density combined with thermal stability is valued, though commercial deployment remains limited compared to conventional aluminum alloys or established intermetallic phases.

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.
