· 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.
