· Al4Co3Ni3

Al4Co3Ni3 is a ternary intermetallic compound combining aluminum, cobalt, and nickel in a 4:3:3 stoichiometric ratio. This material belongs to the family of lightweight multi-principal-element alloys and intermetallics being investigated for high-temperature structural applications where conventional superalloys or aluminum alloys reach their limits. The compound is primarily of research and development interest rather than established production use, with potential applications in aerospace and thermal engineering sectors where superior strength-to-weight ratios and elevated-temperature stability are critical.
