Titanium is used in alloys with aluminum, molybdenum, manganese, and iron. Most of these alloys are used in the aerospace industry such as airframes and engines. It is used because it is strong, lightweight, and has the ability to withstand extreme temperatures.
	Titanium is as strong as steel and much lighter. It is twice as strong as aluminum and nearly as resistant to corrosion as platinum.
	Titanium is also used in joint replacement parts such as hip, ball and joint sockets.
	Titanium has excellent resistance to sea water so it is used for propellar shafts, rigging, and other parts of a ship exposed to salt water. Titanium anodes coated with platinum provides cathodic protection from corrosion.
	Titanium paint reflects infrared radiation so it is extensively used in solar observatories where heat could cause poor viewing conditions.
	Titanium dioxide has an optical dispersion higher than a diamond.
	Titanium dioxide is also used in paint because it has good covering power.
	And finally, Titanium is the main element used in making the Apple Titanium G4 Laptop.
