Medical titanium
Medical titanium alloy titanium implants in the human body for medical devices, artificial organs and prostheses or adjuvant therapy equipment. There titanium 6 aluminum 4 vanadium, titanium, aluminum 5 2.5 Sn, ELI titanium 6 aluminum 4 vanadium alloy. They have high specific strength and mechanical properties close to human bone strength is far superior to titanium, also resistant to fatigue, excellent corrosion resistance and biocompatibility characteristics.
A density of 4.506-4.516 g of buy titanium sheet / cm (20 ℃), but lower than the higher iron aluminum, copper, nickel. However, the intensity ratio of the first metal is located, is three times the stainless steel is aluminum [colored leads: ADC12 aluminum alloy ingot] of 1.3 times. Melting point of 1668 ± 4 ℃, latent heat of fusion 3.7-5.0 kcal / gram atom, boiling point 3260 ± 20 ℃, latent heat of vaporization 102.5-112.5 kcal / gram atom, the critical temperature 4350 ℃, the critical pressure of 1130 atmospheres. Thermal conductivity of titanium and poor, similar or slightly lower than stainless steel, titanium superconducting, the superconducting critical temperature of pure titanium 0.38-0.4K. At 25 ℃, titanium heat capacity of 0.126 cal / g · atom degrees enthalpy 1149 cal / g atom, the entropy of 7.33 cal / g · atom degrees, titanium bar supplier is paramagnetic, permeability of 1.00004. Titanium has plasticity, high elongation up to 50-60% titanium, reduction rate of 70-80%, but lower intensity, not as a structural material. The presence of impurities in titanium, a great influence on the mechanical properties, in particular interstitial impurities (oxygen, nitrogen, carbon) can greatly increase the strength of titanium, significantly reducing its ductility. Titanium as a structural material having excellent mechanical properties, which is strictly controlled and adding an appropriate amount of impurities and alloying elements to achieve.

Titanium performance and major application fields
Titanium performance and major application fields
First beneficiation technology needed to enhance and improve the quality of titanium in titanium concentrate; the second is to achieve recovery of titanium and vanadium, while direct reduction of new processes need to be further improved, after the successful application of titanium tubes and vanadium utilization will increase substantially and create for rare metals recycling chromium, nickel, copper, gallium and other conditions; third is to enhance the utilization of blast furnace slag, put a lot of our Sefstromite as iron, steel with titanium recovery of less than 25%, resulting in a lot of waste of resources, it is necessary to break through the high titanium slag recycling technology; Fourth, the development of high-end applications titanium, vanadium alloys, open the breadth and depth of the market, increase the demand as soon as possible.
Titanium in the air at normal temperature is very stable. When heated to 400 ~ 550 ℃, the solid outer layer of an oxide film is generated, since the effect to avoid further oxidation of maintenance. Titanium absorbs oxygen, nitrogen, hydrogen can be very strong, such a gas is a very harmful impurity metal titanium, even if little content (0.01% to 0.005%) can seriously affect its mechanical function.
Mechanical properties of titanium that is known as the mechanical function is associated with a very pure. High titanium machining function with excellent elongation, shortening section rate is good, but low intensity, discomfort collaborative planning information. Commercially pure titanium rods containing an excessive amount of impurities, has high strength and plasticity, suitable for production planning information.
In the compounds of titanium to titanium dioxide (TiO2) is most practical value. Ti02 on the human body was lazy, non-toxic, it has a series of excellent optical properties. Ti02 opacity, gloss and whiteness, refractive index and scattering force, hiding power, good dispersion, pigment made of white powder, commonly known as titanium dioxide, the use of a wide range.

Titanium and titanium tube and vision in the use of desalination industry analysis
Titanium and titanium tube stock and vision in the use of desalination industry analysis
According to the "Twelfth Five-Year" period desalination industry development goals by 2015, China's desalination capacity will increase 3 to 4 times. Desalination capacity doubling means double the investment, that in the coming years the country will increase investment in the desalination industry, and therefore, our desalination industry will usher in a period of rapid development.
Titanium and titanium tube as an important raw material desalination industry applications, with the rapid development of the desalination industry, China's titanium industry will usher in new opportunities and development opportunities. For desalination technology and applications of titanium and its alloys in seawater desalination industry overview, and titanium and its alloys in the foreground application desalination industry is analyzed.
Of course, the desalination industry as new applications of titanium market, opportunities and challenges. We believe that under the strong support of national policy,titanium tube and its alloys will be widely used in water desalination project, which is to open up new applications of titanium market will play a great role.
We know that, as the "Ocean metal" titanium and its alloys have excellent corrosion resistance in seawater, natural water is all most corrosion-resistant metal material, the corrosion resistance of stainless steel in seawater is 100 times and low density, high strength, good heat resistance. Therefore, material properties, reliability, service life, maintenance and other aspects into account, titanium and its alloys is undoubtedly the most competitive desalination plant material. Titanium used in desalination device comprises a heat exchanger, brine heaters, condensers, distillation, evaporators, pumps, valves, pipes, etc.
