Oct 18 2018 · 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.
