Titanium is a common material found in a myriad of products including watches, drill bits, laptops, and bicycles, just to name a few. In pure form, it is lustrous and silvery-white in appearance. It has a melting point of 1,660°C, a density of 4.5 g/cc, and a vapor pressure of 10-4 Torr at 1,453°C. It is a sturdy material which is easily fabricated when heat is applied. Its strong, lightweight characteristics and excellent corrosion resistance make it ideal for ocean liner hulls, aircraft engines, and designer jewelry. Titanium is biocompatible so it can be found in surgical tools and implants. Titanium is generally evaporated in vacuum for the purposes of wear and decorative, semiconductor, and optical coatings.
