Titanium, which is a very strong and light metal, is as strong as steel but 45% lighter than steel. It is the ninth most abundant element in the crust. Most of them are found in the minerals rutile (TiO2), ilmenite ( FeTiO3) and sphene ( CaTiSiO5). There are five stable isotopes of titanium in nature: 46Ti, 47Ti, 48Ti, 49Ti and 50Ti.
Titanium alloys are used in aircraft (including helicopters), armor plating, naval ships, spacecraft and missiles. Titanium alloys do not fatigue easily, are strong and are resistant to corrosion so they are perfect for use in the above items.
Most titanium is converted to titanium oxide (TiO2). This is the white pigment found in toothpaste, paint, paper and some plastics. Cement and gemstones also contain titanium oxide. Fishing rods and golf clubs are also made stronger through the use of titanium oxide. Titanium carbide is used to make tool bits.
