TIMETAL 5111 (pronounced 5 triple 1) is a near alpha titanium alloy of intermediate str ength. This alloy has been designed for high toughness, good weldability, stress-corrosion cracking resistance, and room temperature creep resistance. TIMETAL 5111 is ideally suited for applications in marine environments where toughness and corrosion resistance are essential. The alloy has been produced on a commercial scale. Forging and machining characteristics of TIMETAL 5111 are very similar to TIMETAL® 6-4. TIMETAL 5111 was developed jointly with the Navy, and has been selected as the material of choice for a submarine application. TIMETAL 5111 is included in the ASTM standards as ASTM Grade 32.
