AlFe2Ni is an intermetallic compound combining aluminum, iron, and nickel in a 1:2:1 stoichiometric ratio, belonging to the family of lightweight metallic intermetallics. This material is primarily of research interest for high-temperature structural applications where the combination of low density with iron and nickel strengthening offers potential advantages over conventional aluminum alloys or nickel-based superalloys. AlFe2Ni represents an exploratory approach to developing advanced materials for aerospace and automotive sectors where weight reduction and thermal stability are critical; however, practical industrial adoption remains limited compared to established alternatives, making it most relevant for engineers evaluating next-generation alloy systems or conducting feasibility studies in weight-critical applications.
