TIMETAL® 10-2-3 HIGH-STRENGTH FORGING ALLOY TIMETAL 10-2-3 is a TIMET developed, high-strength, deep hardenable forging alloy useful for airframes and engines. Metallurgical^ it is a near beta alloy. It offers the opportunity to use near-net shape forging techniques and has excellent strength-toughness combinations. TIMETAL 10-2-3 has very high fatigue life and is well-suited for safe-life designs. Current applications for TIMETAL 10-2-3 encompass numerous aircraft structural parts, including landing gear components.
