PURPOSE:To improve corrosion resistance against nonoxidizing acid and resistance to crevice corrosion by incorporating prescribed percentage of ruthenium, nickel, tungsten, and molybdenum. CONSTITUTION:The titanium-base alloy consists of, by weight, >=1 kind selected from 0.005-2% ruthenium, 0.01-2% nickel, 0.005-0.5% tungsten, and 0.01-1% molybdenum and the balance titanium. This alloy excels in the durability, e.g., under a nonoxidizing acid (hydrochloric acid, sulfuric acid) environment and has superior resistance to crevice corrosion which occurs in a solution containing chlorine ions.
