The largest use of titanium is in the form of titanium(IV) oxide. It is extensively used as a pigment in house paint, artistsâ paint, plastics, enamels and paper.
Titanium is used to make hip replacements. Titanium is a light metal but very strong, e.g. it is as strong as steel but 45% lighter. For these properties it is used to make lightweight alloys for aircraft, bikes and laptop computers.The compound Titanium dioxide (TiO 2) absorbs UV light and is used in sunscreen.itanium is resistant to corrosion by sea water and therefore is used on parts of ships. The non-reactive properties of titanium make it ideal for use in the body as hip replacements and pacemakers, which won't be attacked by body fluids.
