Titanium aluminum is a silvery-white metal, it has many excellent properties. The density of titanium 4.54g/cm3, 43% lighter than steel, light metal magnesium is a little heavier than the famous. Mechanical strength is not much different from the steel, twice times more than aluminum, five times larger than magnesium. TI high temperature, melting point 1942K, 1000K higher than gold, than steel 500K.
Titanium belonging to the chemical properties of more reactive metal. Heating and O2, N2, H2, s and halogen and other non-metallic effect. At room temperature, Titanium is easy to generate a very thin layer of dense oxide protection film, resistant to strong acid or aqua regia, showed strong resistance to corrosion. Therefore, the metal in the acidic, alkali, salts in a solution of titanium became riddled with problems and was left intact.
Liquid titanium can dissolve almost all metals, so that it can be a variety of metals to form alloys. In TI added steels, titanium steel tough and elastic. Titanium metals Al, Sb, Be, Cr, Fe or generate interstitial compounds such as intermetallic compounds.
Made of titanium alloy aircraft heavier than other metals as more passengers more than more than 100 people. Submarine made of both seawater corrosion resistance and resistance to deep pressure, its depth than stainless steel submarine 80%. Also, Titanium is not magnetic, not by mine found, with very good care.
TI has a "biophile" '. In the human body, can resist the corrosive and toxic secretions, adapted to any sterilization method. So it is widely used in medical devices, artificial hip joints, knee joints, shoulder joints, stress joints, skull, active heart valves, bones clips. When the inclusion of new muscle fibers in these "Titanium bone" when these titanium bone begin to maintain the body's normal activities.
