· Al4 La2

Al₄La₂ is an intermetallic compound belonging to the aluminum-lanthanum system, combining a lightweight aluminum matrix with rare-earth lanthanum for enhanced properties. This material is primarily investigated in research contexts for lightweight structural applications and advanced alloy development, where the rare-earth addition can improve high-temperature strength, creep resistance, and thermal stability compared to conventional aluminum alloys. Its practical deployment remains limited, with most development focused on aerospace and high-performance engine components where weight reduction and elevated-temperature performance justify the cost and processing complexity of rare-earth intermetallics.
