AlFeNi2

AlFeNi2 is an intermetallic compound composed of aluminum, iron, and nickel, belonging to the family of lightweight metallic intermetallics that combine high strength with relatively low density. This material is of primary research interest for aerospace and automotive applications where weight reduction and elevated-temperature performance are critical; it represents an alternative approach to conventional aluminum alloys and nickel superalloys, though it remains less widely commercialized than established alternatives due to brittleness and manufacturing challenges inherent to intermetallic phases.
