A titanium alloy may be characterized by a good oxidation resistance, high strength and creep resistance at elevated temperatures up to 750° C., and good cold/hot forming ability, good superplastic forming performance, and good weldability. The alloy may contain, in weight percent, aluminum 4.5 to 7.5, tin 2.0 to 8.0, niobium 1.5 to 6.5, molybdenum 0.1 to 2.5, silicon 0.1 to 0.6, oxygen up to 0.20, carbon up to 0.10, and balance titanium with incidental impurities.
