ScAl2Cu
metal· JVASP-156188· ScAl2Cu
ScAl2Cu is an intermetallic compound combining scandium, aluminum, and copper, representing a lightweight metallic system with potential for aerospace and structural applications. While not yet widely commercialized, this material belongs to an emerging class of scandium-aluminum alloys being researched for their combination of low density and high stiffness, offering engineers an alternative to conventional aluminum alloys where weight reduction and structural rigidity are critical. The addition of copper as a ternary element suggests enhanced strength or wear properties compared to binary ScAl systems, making it of interest for advanced engineering applications requiring optimized strength-to-weight performance.
