TiAl2 is an intermetallic compound in the titanium-aluminum system, representing a lightweight metallic material with a defined stoichiometric composition. This compound is primarily of research and development interest for high-temperature structural applications where the combination of low density and intermetallic strengthening mechanisms offers potential advantages over conventional titanium alloys, though it remains less commercially established than Ti-Al solid solutions used in aerospace.
