· ScAlNi2

ScAlNi2 is an intermetallic compound combining scandium, aluminum, and nickel, belonging to the family of lightweight metallic compounds with potential for high-strength applications. This material appears to be primarily in the research and development phase, with interest in aerospace and structural applications where the combination of modest density and stiffness could offer weight savings compared to conventional alloys. The ternary composition suggests investigation into novel intermetallic systems that might provide improved mechanical performance or functional properties for specialized engineering roles.
