Titanium, a very strong and durable mineral, is used in making bikes, automobile parts, and sports equipment.

Titanium is a strong, light  metal. It is as strong as steel and twice as strong as aluminum but 45% lighter than steel and highly resistant to corrosion.  It is used in making alloys and is mostly added to steel because it increases the strength and resistance to corrosion of steel.

 Titanium - steel alloys are particularly useful in spacecraft and aircraft applications which account for about 65% of all Titanium sold. These alloys find a host of other applications  such as in manufacture of jewelry, bicycles, golf clubs, various sports equipment and also in the medical field as artificial hips, knees and specialized dental implants.
