Titanium

Atomic number: 22

Symbol: Ti

Category: transition metal

Density at 25°C: solid 4.506 g·cm−3

Titanium is a well known element in the contemporary world, even inspiring popular music.  Although often added to metals as an alloy, in it's elemental form it is as strong as steel but some 45% lighter.

It has the highest strength-to-density ratio of any metallic element.

Titanium is often alloyed with iron, aluminium, vanadium, molybdenum and then used in a wide range of applications especially aerospace industries in engines.

Discovered in Cornwall, Great Britain, by William Gregor in 1791 titanium was named by Martin Heinrich Klaproth of the Titans of Greek mythology.
