Titanium is an extremely useful corrosion-resistant material. Titanium obtains its corrosion resistance in the same way as aluminum and copper — through a passive oxide film that forms on its surface, protecting the remaining interior of the material. As a result, titanium can endure very harsh conditions for long periods of time.

Corrosion-Resistant Titanium The various grades of ATI unalloyed titanium exhibit differences in formability. Grades 1, 11 and 17 titanium, which are the softest and most ductile grades, exhibit the greatest formability. The slightly greater strengths of Grades 2, 7 and 16 titanium are still quite formable, but less so than Grades 1, 11 or 17.
Titanium is light weight, exceptionally corrosion resistant and often exceeds the corrosion resistance of stainless steels in most environments. Of the four commercially pure (C.P.) titanium grades, Grade 2 is the alloy of choice for most industrial applications that require good ductility and corrosion resistance.
