uses of titanium
Alloys of titanium are mainly used in aerospace, aircraft and engines where strong, lightweight, temperature-resistant materials are needed. As a result of its resistance to seawater, (see above) titanium is used for hulls of ships, propeller shafts and other structures exposed to the sea.
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).
