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.

R & D status Titanium

Relative titanium sponge, since the development of aerospace technology, has been very active in research and development of titanium. From basic research to study properties of the alloy, to applied research have made great progress.

Basic research, interstitials impact strength and bulk modulus of titanium research, composite interface behavior finite element simulation study, ordered alloy strengthening research, alloys interaction of atoms and vacancies, etc. have made progress. In order to meet the performance requirements of applications in different fields of titanium wire manufacturers, alloy design display space, with remarkable results. Used in aerospace field BT 3 7 alloy, NI N CT 2 0 alloy, NI NT i a 600 alloy, T i a 60 alloy, "I T1 5 D alloy, NI NT i a 40 alloy, NI NT i a 26 alloy, and NI N TP a 650 alloy is representative of the new grade alloy materials research at home and abroad in recent years, to meet the different components of the material application performance requirements, and some can reduce costs, reduce quality study of high temperature titanium alloys (such as T i 5 3 3 1 1 S) is also a hot spot [16]; apply to ships in the field of T imeta l 5 1 1 alloy, NI NT i -B 1 9 alloy and NI NT i have a 91 alloy significantly improved in toughness, corrosion resistance and sound transmission, etc., for large ships (such as aircraft carriers) manufacturing and marine industry has a positive role in promoting development in the biological field mainly uses Z r, N b, T a, P d and sn as grade 1 titanium wire element to enhance the mechanical properties and biocompatibility, such as T i a 3 5 Z r - l ON b alloys and T i a 2 9 N b a 1 3 T a a 4. 6 Z r alloys, etc. In recent years, the development of bone material, Tsinghua University is a typical representative of the biological field applications. civilian areas widely used a golf club called KS -T il 9 grades of alloy, making the cost of a substantial decline, quality.

In recent years, due to the promotion of civilian titanium, titanium applied research in the construction, automotive, marine engineering, medical, and sports and other aspects began to increase, especially in the field of application of desalination has attracted wide attention, medical titanium 1, C 2 0 ( T i a 6 A 1 -7 N b) the products have been in clinical use.

titanium welding wire operation essentials

1, manual welding, weldment between the wire and should be kept to a minimum angle (10 ~ 15 °).medical titanium alloy Wire along the pool front smooth, uniform into the pool, not the end of the wire out of the argon gas reserves.
2, titanium welding wire welding torch without substantially horizontal swing, the swing when required, the frequency is lower,Medical titanium bar the swing amplitude is not too large, in order to prevent the effects of the protection of argon.
3, when the arc and weld finishing off, to continue through argon, until the weld metal and heat affected zone is cooled to remove the gun before the time below 350 ℃.
