Al2 Fe4

Al₂Fe₄ is an intermetallic compound in the aluminum-iron system, characterized by a defined crystal structure and a high iron content relative to aluminum. This material belongs to the family of aluminum-iron intermetallics, which are typically brittle ceramics or hard phases rather than structural alloys, and is primarily studied in research contexts for understanding phase behavior and potential hardening applications. Industrial interest centers on wear-resistant coatings, strengthening phases in composite materials, and high-temperature applications where the iron-rich intermetallic phase can contribute hardness and thermal stability to aluminum-based systems.
