Al18Fe7Ni75

Al₁₈Fe₇Ni₇₅ is an intermetallic compound combining aluminum, iron, and nickel in a high-nickel matrix, belonging to the family of ternary intermetallics with potential for high-temperature or specialty applications. This composition is primarily explored in research contexts for applications requiring combinations of lightweight character (from aluminum) with enhanced strength or thermal stability (from iron and nickel contributions). The material represents an experimental alloy rather than a commercial standard, and its utility depends on how the intermetallic phases balance brittleness against thermal or mechanical performance gains over conventional binary or ternary alloys.
