Al8Fe5

Al8Fe5 is an intermetallic compound in the aluminum-iron system, representing a brittle, hard phase that forms at specific compositional ratios. This material is primarily of research and development interest rather than a widely commercialized engineering alloy, as it exhibits the characteristic brittleness typical of aluminum-iron intermetallics. When incorporated as a reinforcing phase in aluminum matrix composites or cast aluminum alloys, Al8Fe5 can improve hardness and wear resistance, though its low ductility limits its use in load-bearing structural applications requiring toughness.
