Corrosion-resistant titanium alloy

Abstract

A corrosion-resistant Ti alloy includes Pd in an amount of 0.020-0.050 mass %, and includes one or more platinum group elements other than Pd in an amount of one-third or more of the mass of Pd, with the balance being composed of allowable components and Ti. This alloy exhibits excellent corrosion-resistance. If the Fe content is 0.05% or less and O content is 0.05% or less, excellent cold-workability can be obtained. If the Pd content is 0.030% or less, not only cold-workability and corrosion-resistance but also resistance against hydrogen absorption can be obtained.
