TIMETAL® 6-2-4-2 MEDIUM-STRENGTH, ELEVATED TEMPERATURE ALLOY
Ti-6Al-2Sn-4Zr-2Mo-0.08 Si

TIMETAL 6-2-4-2 has an outstanding combination of tensile strength, creep strength, toughness, and high-temperature stability for long-term application at temperatures up to 1000°F (538°C). Its primary application is gas turbine compressor components such as blades, discs, and impellers. TIMETAL 6-2-4-2 is also used in sheet metal form for engine afterburner structure and for various hot airframe skin applications. Forging and machining characteristics of TIMETAL 6-2-4-2 are very similar to TIMETAL ® 6-4.
