· Al3Fe2Ni4

Al3Fe2Ni4 is an intermetallic compound combining aluminum, iron, and nickel in a fixed stoichiometric ratio, belonging to the family of lightweight metallic intermetallics. This material is primarily of research and development interest for high-temperature applications where its ordered crystal structure and multi-element composition offer potential for improved strength-to-weight ratios compared to conventional aluminum alloys or nickel superalloys. Industrial adoption remains limited; the material is investigated for aerospace and automotive sectors seeking alternatives to traditional alloys, though its brittleness at lower temperatures and complex processing requirements present engineering challenges.
