CaMg2Al2 is an intermetallic compound combining calcium, magnesium, and aluminum—a lightweight ternary phase that belongs to the family of magnesium-aluminum alloys with calcium additions. This material is primarily of research and development interest rather than established commercial production, as it represents an emerging candidate in the lightweight structural alloy space where engineers seek to balance low density with adequate stiffness. The addition of calcium to Mg-Al systems is being explored to improve creep resistance, corrosion performance, and thermal stability compared to binary magnesium-aluminum alloys, making it relevant for automotive, aerospace, and powertrain applications where weight reduction is critical.
