Titanium metal connects well with bone, so it has found surgical applications such as in joint replacements (especially hip joints) and tooth implants. 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 as strong as steel, but much lighter. It is twice as strong as aluminium. It is nearly as resistant to corrosion as platinum. Titanium is a component of joint replacement parts, including hip ball and sockets. These may last for 20 years or so.Titanium is used in dental implants because it is able to osseointegrate (an unusual ability by which titanium fuses with bone tissue, perhaps through the titanium oxide layer on tianium metal).itanium is as strong as steel, but much lighter.
