Al₃Fe is an intermetallic compound formed between aluminum and iron, belonging to the family of aluminum-iron phases commonly encountered in aluminum alloys and cast structures. This brittle, high-density intermetallic phase typically appears as a secondary constituent in commercial aluminum alloys rather than as a standalone engineering material, where it influences overall alloy strength and wear resistance. Engineers encounter Al₃Fe primarily in cast aluminum components and wear-resistant coatings, where its high hardness is valued despite limited ductility; it is also of interest in composite reinforcement and additive manufacturing research as a strengthening phase in aluminum matrix composites.
