Titanium Performance

Titanium Performance


         1, low density, high specific strength
         The density of titanium is 4.51g / cm3, higher aluminum and less than iron, copper, nickel, but the head of the metal strength located
         2, corrosion resistance
         Titanium is a very reactive metal, which is very low equilibrium potential, thermodynamic corrosion tendency in the medium is large, but in fact the titanium is very stable in many media, such as titanium in an oxidizing, neutral or weakly reducing medium is corrosion resistance. This is because titanium has a great affinity for oxygen, in the air or an oxygen-containing medium, the surface of titanium to produce a dense, strong adhesion, inert large oxide film, protects the titanium substrate from corrosion, even if the mechanical wear will soon heal or regenerate. This shows that titanium is a metal with a strong passive tendencies. Medium temperature below 315 * c titanium oxide film remains this feature.
          3, good heat resistance
          New titanium alloy wire under long-term use of 600 * C or higher temperatures.

          4, good low temperature performance
         Its strength with decreasing temperature increase, but the plastic change is not large, good ductility and toughness at low temperature -196-253 ℃. Avoid cold brittle metal, is an ideal material for cryogenic vessels, tanks and other equipment.

          5, anti-damping properties.
          After medical titanium alloy subjected to mechanical vibration, electrical vibration, compared with steel, copper, its vibration damping longest, do take advantage of this performance titanium fork, ultrasonic vibrating element grinder medicine and advanced audio speaker vibration film.

          6, non-magnetic, non-toxic
          Titanium is non-magnetic metal, a large magnetic field will not be magnetized, non-toxic and with human tissue and blood have good compatibility, they were using the medical profession.

          7, the tensile yield strength of its proximity
         This performance titanium shows its yield ratio (tensile / yield strength) high, indicating that the metal material is too poor in the molding of plastic deformation, due to the ratio of yield strength and elastic modulus of titanium, causing titanium molding rebound capacity.
