Description

Titanium UNS R54810 is a near Alpha Alloy that was primarily designed for use at elevated temperatures – up to 455 degrees centigrade. It offers the highest modulus and lowest density of all Titanium alloys. It has good creep strength and it’s weldable by the inert gas fusion and resistance-welding processes. Titanium UNS R54810 is used in the annealed condition for such applications as airframe and jet engine parts that demand high strength, superior creep resistance and a good stiffness-to-density ratio. The machinability of this grade is similar to that of Titanium 6Al-4V.
