Ti 6-2-4-2 (Ti-6Al-2Sn-4Zr-2Mo)

Ti 6-2-4-2 (Ti-6Al-2Sn-4Zr-2Mo, UNS R54620) is a near-alpha titanium alloy developed for high-temperature service, combining high strength with excellent creep resistance and thermal stability. A small silicon addition (0.06-0.10%) further improves its creep strength. It retains its mechanical properties up to approximately 540°C (1000°F), well above the service range of Ti-6Al-4V, and is used for compressor blades, discs and cases in gas turbine engines, as well as afterburner and hot airframe sheet components. DASM supplies Ti 6-2-4-2 as sorted, analyzed, cut and shot-blasted melting feedstock.
