· JVASP-14906· CaAl2Si2

CaAl₂Si₂ is an intermetallic compound combining calcium, aluminum, and silicon—a lightweight ceramic-metallic material that bridges metallic and ceramic properties. This compound is primarily of research and developmental interest for aerospace and structural applications where weight reduction and thermal stability are critical; it represents the family of complex intermetallics being explored as alternatives to conventional aluminum alloys and titanium for high-temperature or weight-sensitive designs. The material's potential lies in its low density combined with moderate stiffness, making it a candidate for next-generation lightweight structural components, though industrial adoption remains limited compared to more mature alloy systems.

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.
