· Al5Ir4Ni

Al5Ir4Ni is an intermetallic compound combining aluminum, iridium, and nickel in a defined stoichiometric ratio, belonging to the family of multi-component metallic intermetallics. This material is primarily of research and development interest rather than widespread industrial use, explored for high-temperature structural applications where the combination of light weight (aluminum) and refractory elements (iridium, nickel) offers potential advantages in extreme environments. Its development context reflects interest in advanced intermetallics for aerospace and energy applications where conventional superalloys face temperature or weight limitations.
