Titanium is a chemical element. You may find Titanium oxyde (Titanium + Oxygen), Titanium as a metal, Titanium aloyed as a minor element in other metals...
|Suprisingly, it is mostly used as an oxyde. As a white pigment. 95% of Titanium goes for this application.|
As a metal titanium as one of the best strengh / weight ratio. It is as strong as some stainless steels and quite half the weight. Another intersting caracteristic is its very high resistance to corrosion. It price stay high even if it is lower nowdays than in the past.
Titanium metal can be used in nearly all upscale fields where you need something quite as strong as steel but more lightweight and/or corrosion resistant.
One of the most important historical use of Titanium is aerospace. Yet Titanium is not cheap and Aluminium does the job well. So that commercial aircraft strucures are in Aluminium rather than Titanium while it is still used on many parts. You can even find more of it in military applications.
Marine military device can makes use of it strengh, it weight and it corrosion resistance. There is submarines with a Titanium hull.
It is also used on some high quality sporting goods for the same reasons.
Glasses are ofter made with Titanium because it makes it possible to have thin and lightweight frames.
Jewellery is another application. Titanium has a reputation of high durability and prices. This raise an interest.
Chemical industry makes a good use of Titanium for tanks, pipes, devices... The main reason is its corrosion resistance and then its strengh.
Medicine makes a good use of Titanium. You can put Titanium implants in a human body, it will even joint with bones.
Titanium is mixed in small quantities in some steel, aluminium, cooper... alloys. In many cases it will improve microstructure quality and material strengh.
