Titanium
Titanium, named for the Titans, sons of
the Greek gods, Titanium, when pure, is a lustrous, grayish white metal. It has
a low density, good strength, is easily fabricated, and has excellent corrosion
resistance. It is mainly used in jewelry as an accent metal in Men’s jewelry.
Its inertness and ability to be attractively colored also make it a popular
metal for use in body piercing. Most titanium is principally used for aircraft
and missiles where lightweight strength and ability to withstand extremes of
temperature are important. Titanium is as strong as steel, but 45% lighter. It
is 60% heavier than aluminum, but twice as strong. It is the ninth-most
abundant element in the Earth's crust. Titanium was discovered at Creed,
Cornwall in England by amateur geologist Reverend William Gregor in 1791.
Significant titanium ore deposits exist
in Australia, Scandinavia, North America, Africa and Malaysia.
