· Al4(CuNi)3

Al₄(CuNi)₃ is an intermetallic compound combining aluminum with copper and nickel, belonging to the family of aluminum-based intermetallics. This material is primarily of research and developmental interest rather than widely commercialized, with potential applications in aerospace and high-temperature structural applications where lightweight, thermally stable compounds are valuable. Its appeal lies in the possibility of combining aluminum's low density with the strengthening and thermal properties contributed by copper and nickel additions, though practical engineering adoption remains limited compared to conventional aluminum alloys or nickel-based superalloys.
