Titanium is considered to be one of the strongest metals. Its strength, heat, water and salt resistance, and its light weight make it the ideal metal for a variety of applications. These applications range from jewelry and dental implants to airplanes and ships. Pure titanium is strong and corrosive resistant. Titanium Alloys retain the same strength and corrosion resistance, but takes on the greater flexibility and malleability of the metal it is combined with. Titanium alloys, therefore, have more applications than pure titanium. There are six grades of pure titanium (grades 1,2,3,4,7 and 11) and 4 varieties of titanium alloys. Titanium alloys typically contain traces of aluminum, molybdenum, vanadium, niobium, tantalum, zirconium, manganese, iron, chromium, cobalt, nickel, and copper.

The four grades, or varieties of titanium alloys are Ti 6AL-4V, Ti 6AL ELI, Ti 3Al 2.5 and Ti 5Al-2.5Sn.
