· Al5NiIr4

Al5NiIr4 is an intermetallic compound combining aluminum with nickel and iridium, likely developed for high-temperature structural applications where conventional aluminum alloys reach their limits. This material belongs to the family of advanced intermetallics being investigated for aerospace and high-performance thermal environments, where the addition of iridium provides exceptional oxidation resistance and creep strength compared to nickel-aluminum superalloys alone. Though primarily a research-stage material, it represents the class of refractory intermetallics targeted at applications demanding both lightweight and extreme thermal stability beyond current commercial aluminum and nickel-based alternatives.
