· Al11(CuNi2)3

Al11(CuNi2)3 is an aluminum-based intermetallic compound containing copper and nickel, belonging to the family of complex metallic alloys (CMAs) or quasicrystalline-related phases. This material is primarily of research and developmental interest rather than established in high-volume production, with potential applications in high-temperature structural use and wear-resistant coatings where its intermetallic strengthening and phase stability could provide advantages over conventional aluminum alloys. Its notable appeal lies in combining aluminum's light weight with copper and nickel's high-temperature strength and oxidation resistance, though processing and brittleness challenges typical of intermetallics have limited its adoption compared to more conventional aerospace and automotive alloys.
