· Ti2AlV

Ti2AlV is an intermetallic titanium aluminide compound combining titanium and aluminum in a stable crystal structure, representing a class of advanced lightweight metals engineered for extreme-temperature service. This material is primarily used in aerospace propulsion systems—particularly jet engine compressor blades and casings—where its combination of low density and high-temperature strength significantly reduces fuel consumption compared to conventional nickel superalloys. Engineers select titanium aluminides like Ti2AlV for applications demanding weight reduction at elevated temperatures, though careful processing is required to manage brittleness and oxidation resistance in service.
