An alpha-beta, titanium-base alloy with improved ductility at high strength levels compared to commercially available alloys, such as Ti-17. The alloy exhibits at least a 20% improvement in ductility at a given strength level compared to Ti-17. The alloy comprises, in weight %, 3.2 to 4.2 Al, 1.7 to 2.3 Sn, 2 to 2.6 Zr, 2.9 to 3.5 Cr, 2.3 to 2.9 Mo, 2 to 2.6 V, 0.25 to 0.75 Fe, 0.01 to 0.8 Si, 0.21 max. Oxygen and balance Ti and incidental impurities.
