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.

Current use of vanadium and titanium resource

Vanadium Titanium is an important strategic material, size and level of development of vanadium and titanium industry, the national economy and national defense construction has a significant impact. Our bears abundant vanadium-titanium magnetite resources, mainly in Panzhihua, Sichuan and Hebei Chengde. Panxi vanadium and titanium grade 2 resources are our most enriched regions, vanadium-titanium magnetite prospective reserves of over 10 billion tons, of which vanadium, titanium reserves accounted for 63% and 90.5%, respectively, the country, in third place in the world, the first one .

Of vanadium and titanium in the use of resources and materials preparation and processing technology has initially formed a relatively complete system. Nevertheless, due to the strength and depth of scientific understanding is still lagging behind in industrial production practices, in particular the important advantage of lower degree of extraction of the metal elements (iron ore terms, vanadium recovery is not more than 50%; with ore meter, recovery of titanium does not exceed 10%), a number of important scientific and technological issues remain unresolved, the relevant scientific issues also need to be examined. Currently the core issue of vanadium and titanium plate for sale resources exist metallurgical process is the process of vanadium and titanium metallurgy valuable component to strengthen the migration rule and the effective separation of missing and incomplete theory.
