Titanium is very reactive, and because of this it is often used for alloying and deoxidizing other metals.
Titanium is a more powerful deoxidizer of steel than silicon or manganese.
This combination of high strength and low weight makes titanium a very useful structural metal. Titanium also features excellent corrosion resistance, which stems from a thin oxide surface film which protects it from atmospheric and ocean conditions as well as a wide variety of chemicals. Fabrication Titanium is rather difficult to fabricate because of its susceptibility to oxygen, nitrogen, and hydrogen impurities which cause the titanium to become more brittle. Elevated temperature processing must be used under special conditions in order to avoid diffusion of these gasses into the titanium. Titanium can also be cast, which must be done in a vacuum furnace because of titanium's reactive nature.
