What does titanium mean?
Titanium is a chemical element, symbol Ti, with atomic number 22. It is a silvery-white transition metal valued for its low density, high strength-to-weight ratio, and resistance to corrosion. In ordinary English, the word can refer either to the element itself or to titanium metal used in aerospace equipment, medical implants, sports goods, jewelry, and other specialized products. Compounds have distinct meanings: titanium dioxide is a widely used white pigment, while titanium alloy refers to metal containing titanium combined with other elements. The material is especially associated with applications in which low weight and durability are important. Its biocompatibility also makes some titanium alloys useful in implants that remain in the human body. Titanium is therefore both a precise scientific term and a familiar word in modern manufacturing, medicine, and engineering.
nounA chemical element and silvery-white transition metal, symbol Ti, atomic number 22, used in lightweight alloys and other specialized materials. In compounds such as titanium dioxide, the name denotes a titanium compound rather than the elemental metal.
- The chemical element titanium, especially the silvery-white metal used in alloys, medical implants, and other applications requiring a combination of low density, strength, and corrosion resistance.
"The aircraft's landing gear was made from a titanium alloy."
"The aircraft's landing gear was made from a titanium alloy."
"A coating of titanium dioxide gives the paint its bright white pigment."
Titanium is normally an uncountable mass noun, so plural agreement is avoided when speaking of the material generally. The plural titaniums is uncommon and may distinguish separate samples, grades, or objects described as titanium.
"The laboratory compared titaniums from two different suppliers."
Titanium has a legendary name and a modern engineering reputation: it honors the Titans of Greek mythology while helping make aircraft, implants, and high-performance equipment possible.

Where does titanium come from?
The name titanium was coined in the late eighteenth century from the Titans, the powerful primordial figures of Greek mythology. It belongs to the same mythological family as Titan, titanic, and titanosaur, all of which draw on Greek forms associated with the Titans. The suffix -ium was also widely used in the names of chemical elements, following the naming conventions established in modern chemistry.
How titanium is actually used
Titanium is normally an uncountable mass noun when referring to the material. It is also used attributively in established compounds such as titanium alloy and titanium dioxide. British and American pronunciations are essentially the same.
Easily confused with titanium
Titanium is a chemical element and metal, whereas a titan is a person of exceptional strength or importance, after the Titans of Greek mythology.
