Titanium (Ti, atomic number 22) is a lustrous silver-white metallic element used principally to make lightweight, resistant alloys. Titanium metal and its alloys are light in weight and have very high tensile strength, even at high temperatures. These metals are utilized in aircraft, spacecraft, naval ships, guided missiles, and lightweight armor plate for tanks.
Titanium has many desirable properties of notable strength and durability and is immune to corrosive attacks by saltwater and marine atmosphere and exhibits exceptional resistance to a broad range of corrosive gases, acids and alkalis. Pure titanium is as strong as steel yet nearly 50% lighter. With all its properties, titanium is perfect material for making a durable and jewelry, say, ring, pendant . . . etc.
