Common Name
General Information
Ti-10V-2Fe-3Al is a near beta alloy capable of a wide range of strengths depending on heat treatment applied. The alloy has excellent forgeability, high toughness and good hardenability which allows good properties in sections to 5″ thick. Ti-10V-2Fe-3Al is used for high strength aircraft forgings. Its excellent forgeability allows it to be used in near-net shape forging applications. Ti-10V-2Fe-3Al is available in billet, bar and plate.
