LiSc2Au

LiSc2Au is an intermetallic compound combining lithium, scandium, and gold—a ternary metal system that belongs to the class of lightweight, high-modulus alloys. This is primarily a research material studied for fundamental materials science and metallurgical behavior rather than an established commercial product. Interest in this compound centers on the combination of lithium's low density with scandium and gold's strengthening effects, positioning it as a candidate for advanced aerospace or high-performance applications where stiffness-to-weight ratio is critical, though practical use remains limited by processing complexity, cost, and limited data on long-term performance.
