Ti-6Al-4V annealed is a two-phase titanium alloy (6% aluminum, 4% vanadium) in a stress-relieved condition offering moderate strength with improved ductility and fracture toughness compared to higher-strength tempers. Widely used in aerospace engine casings, compressor blades, and airframe components where operating temperatures to 300°C and damage tolerance are critical; available in forgings, extrusions, castings, and wrought forms per MIL specifications.
