· Al4FeNi5

Al4FeNi5 is an intermetallic compound in the aluminum-iron-nickel system, characterized by a ordered crystal structure combining aluminum with iron and nickel constituents. This material belongs to the family of lightweight intermetallics and has been studied primarily in research contexts for its potential to offer improved high-temperature strength and stiffness compared to conventional aluminum alloys, though it typically exhibits lower ductility. Industrial adoption remains limited; applications have been explored in aerospace and automotive sectors where weight reduction and elevated-temperature performance are valued, but conventional superalloys and precipitation-hardened aluminum alloys remain the dominant choices due to superior damage tolerance and established manufacturing infrastructure.
