Why Titanium ??? Titanium (Ti) is an exotic material that can be hard to mine very much like diamonds. Ti is extremely strong, lightweight, non corrosive, high crack resistance, Hypo-allergenic exotic metal. This material is used dramatically in the military, aerospace, sea industry's due to it's amazing properties. Ti is quite frequent, but hard to extract, which makes the pure metal fairly expensive. Much better available than the metal itself is titanium dioxide, TiO2, the most widely used white pigment, which you can see on nearly every white painted wall. Titanium dioxide is one of the thermic most enduring molecules and one of only a few that can be found in some stars !!!
