Ti-6Al-2Sn-4Zr-2Mo is a near-alpha titanium alloy with aluminum, tin, zirconium, and molybdenum additions designed for elevated temperature applications requiring creep resistance and thermal stability. The annealed condition provides optimal combination of strength retention at intermediate temperatures (up to ~300°C), good fracture toughness, and formability in sheet form for aerospace engines, compressor blades, and casings.
