Titanium and titanium alloy wire as an important species Titanium series, titanium wires in terms of production, specifications and applications now have made great progress. The general sense of titanium and titanium alloy wire refers to the circular disk form supply titanium products, but also in the form of straight wire supply, the diameter, the division of the rod and wire is not critical, countries are also different. Titanium wire and titanium alloy materials as metal materials in the leader, with a series of other metals unparalleled performance, and therefore has developed rapidly in recent years, and is widely used in high-tech fields quickly aerospace and military industry. United States, Russia, Japan, China and other countries in the world have attached great importance to the research and development of titanium alloy, titanium wire and constantly develop new titanium alloy materials, to expand the application of titanium and titanium alloy. Due to the deepening of research and product range increase, and now a lot of titanium products, such as titanium wire etc. have also been more and more into a variety of civilian consumer goods.

 

Titanium wire forming stable carbides with carbon a higher hardness. titanium wire Growth carbidelayer between titanium and carbon diffusion rate of titanium carbide layer to decide.

The solubility of carbon in titanium is small, at 850X: When the total is 0.3% at 600C and at approximately 0.1% B drops due to the small solubility of carbon in titanium, so that substantially only by titanium carbide layer and the lower fork domain deposited layer to achieve the purpose of surface hardening. Removal of the oxygen must be carried out under conditions of carburizing, the surface layer hardness as carburizing for steel powder used against carbon monoxide or oxygen to form carbon monoxide surface reaches 2700MPa and 8500MPa, and the head. It is easy to peel off.
In contrast to this, in the deoxidation or decarburization conditions, it may be formed in the charcoal thin carburized layer of titanium carbide. This layer hardness 32OUOMPa, conforming to the hardness of titanium carbide. Carburized layer is substantially greater than the depth of the nitrided layer under the same conditions when the nitriding depth with nitrogen. In the oxygen-rich conditions must take into account the effects of oxygen absorption hardening depth. Only under conditions of very thin thickness, titanium wires in a vacuum or argon - methane atmosphere before the toner may penetrate a sufficient adhesion strength comparison, using a gas carburizing agent may form hard and particularly good adhesion titanium carbide hardened layer. While the 950T: and 10201: temperature between the conditions for the formation of hardened exhibition in 50fim between and. With the increase of the thickness of the titanium carbide layer becomes more brittle and tend to flake t To avoid decomposition leaving Rui alkyl carbon inclusions invasion of titanium carbide layer, it should be used about 2% volume fraction Rui alkyl provisions dose additive gas carburizing in an inert gas. When using propane additive use methane is formed when carburizing low surface hardness. When the adhesive force reaches Wu Mao OkPa conditions when using propane gas carburizing, although the measured thickness of the hardened layer is very thin, but with the best wear resistance. Absorption of hydrogen in the gas type carburizer conditions using either, but had to remove it in the vacuum annealing.

Titanium and titanium alloys because of corrosion resistance,titanium wire price  high strength, non-magnetic, high biocompatibility, ultrasound impedance smaller, higher sound transmission coefficient, hydrogen storage and better series of shape-memory function excellent characteristics important value, which in the aerospace, petrochemical, medical and health, automotive, construction, and sports and leisure goods and many other areas had an important purpose. But in recent years because of its continuous development of increasingly numerous varieties, which provide more choice in high-performance industrial supplies and consumer goods applications. The following aspects on the status of the application to the system introduced titanium and titanium alloy wire material.
1983 revision of the standard uniform of titanium into the national standards, simply cancel the name of titanium wire standards, and formulated the GB3623-83 "titanium and titanium alloy wire" standard, standard "chemical composition of the wire rod in line with GB3620-83 (titanium and titanium alloys and chemical composition) provides "that the chemical composition completely deformed titanium and titanium alloys and other materials the same. "Titanium and titanium alloy wire," states: "This standard applies to circular titanium and titanium alloy wire corrosion-resistant parts, electrode materials and welding materials and other uses." That is expressly ordinary wire structure used as the titanium wire.
From titanium standard, China's production of titanium in terms of chemical composition or mechanical properties of titanium have basically reached international advanced level. But no real standards and product titanium wire, titanium wire structure serving as titanium wire the wire, so that our titanium wire lowest in the world. The amount of titanium wire only about 2% of the amount of titanium, it is that 2% of low-quality titanium wire titanium pressure vessel to reduce the overall plasticity reserve, greatly lowered the level of quality titanium pressure vessel. For users titanium pressure vessel, the investment cost titanium pressure vessels eventually high quality using low-cost titanium wire does not make much of an investment savings, and has been low-quality titanium pressure vessel, it should be said, the economy is very uneconomical.

Titanium poor ductility at room temperature, cold forming difficult, although thermoforming technology can be used, titanium round bar but the processing cycle is long and costly. At present, China mainly used titanium forming aircraft, satellites and rocket parts, wherein forming a simple straight line bent parts and flat curve large proportion of the flange member. Due to the small quantities, using the original heating forming technology requires a large amount of heat produced molds and molded parts is restricted furnace size, in order to reduce costs, simplify the process conditions, shortening the titanium sheet production cycle parts, accelerate the development of new models will sheet metal laser forming technique for titanium metal forming, can give full play to the unique advantages of the technology.

 

Chemical composition of the product in line titanium rod for salewith GB / T3620.1 corresponding provisions grades, titanium, TC4 and TC4ELI the H content should be not more than 0.010%. When the demand-side review, the chemical composition and permissible variations should be consistent with the provisions of GB / T3620.2 of. Dimensions product dimensions and tolerances should use the appropriate precision instrument measure, according to customer requirements to ensure that the level of magnification of plus or minus tolerance test was referring to the provisions of GB / T5168's. Medical titanium rod, does not allow cracks, holes, metal or non-metallic inclusions and other visible defects lateral visual low titanium rod times on medical titanium alloy bars. Annealed titanium rods should be uniform transverse microstructure, grain size should be no bigger than 5. High-powered organization Medical Titanium rods annealed condition shall comply with A1 ~ A9.

Titanium and titanium alloys have excellent use titanium bar price properties, is recognized as the world's bio-medical field is excellent metallic material, with the use of stainless steel, cobalt-based alloys and other metal materials, compared with the advantages of a larger application, great room for development. According to the information, the amount of metal material used as human implants gradually increases. Since 1990, only the United States each year for human implant metal parts to reach 2 million or more, including hip, femur piece 2.5%; the European market for external fixation fracture fixation products and booming demand and supply of products to France Germany, Italy and Britain dominated the market in 2004 valued at 280 million dollars, of which internal fixation products accounted for 85.7%. The past 10 years, biomedical materials titanium foil supplier and products market growth rate has remained at 20% to 25% forecast in the next 10 to 15 years, rapid development of medical device industry including bio-medical materials, including, to achieve economies of scale, as the world a pillar industry of the economy.

Domestic titanium and titanium alloy materials, in orthopedics, neurosurgery, cardiovascular system, oral and titanium alloy sheet maxillofacial surgery, cultured outside the human body and other widely used. The past five years, there are a number of enterprises have become the titanium and stainless steel body of the implant manufacturers. Titanium and titanium alloy femoral head, hip, humerus, skull, knee, elbow, shoulder, metacarpophalangeal joints, the jaw and valvular heart, kidney valvular and vascular dilator, splints, prostheses, fastening titanium company screws and other metal pieces of hundreds of transplanted into the human body, and achieved good results, the medical profession to give a high evaluation.

To whether it contains titanium alloying elements can titanium wire be divided into pure titanium and titanium alloys, and titanium and organizations based on their composition and temperature can be divided into α titanium and near α type alloys, (α + β) type alloy, near β type alloy and β-type alloys. Titanium and titanium alloys with different properties can be prepared according to titanium wires the different requirements of wire. Titanium and titanium alloy wire finished generally hard state (Y) and annealed (M).

Titanium is a silvery white metal wire, it has molybdenum bar many excellent performance. The density of titanium wire was 4.54g / cm3, 43% lighter than steel, lighter than the prestigious magnesium slightly heavier. The mechanical strength of steel but with similar, twice as big as aluminum, magnesium than five times larger. Titanium wire temperature, melting point 1942K, higher than gold near 1000K, higher than the steel near 500K. Category titanium wire titanium wire is divided into: titanium wire, titanium wire, titanium wire eyes, straight titanium wire, titanium wire, titanium wire, titanium wire rack, titanium titanium flat bar plate wire, medical titanium wire, medical titanium wire, titanium-nickel alloy wire. Titanium wire specifications.

History of titanium

History of titanium

   1791 British clergyman W. Gregor (Gregor) discovered a new metal elements in black magnetite. In 1795 the German chemist M. H. Carat Preuss (Klaproth) rutile in the study also found that the elements, and is named after the Greek god of the Titans. 1910 American scientist M. A. Hunter (Hunter) for the first time with a sodium reduction TiCI: Preparation of titanium. 1940 Luxembourg scientist W. J. Kroll (kroll) with magnesium reduction TiCl: prepared titanium. Since then, the magnesium reduction method (also known as the Kroll process) and sodium reduction method (also known as Hunt France) became the industrial production of titanium sponge method. In 1948 the United States out of the magnesium reduction process 2t titanium sponge, from reaching industrial scale. Subsequently, the United Kingdom, day / the former Soviet Union and China have also entered the industrial production, one of the major producing country of the former Soviet Union titanium, day / and the United States.
   titanium target is a new metal, because it has a series of excellent features, aviation, aerospace, chemical, petroleum, metallurgy, light industry, power, desalination, ships and everyday appliances are widely used in industrial production, which is hailed for modern metal. Titanium metal production from 1948 has only half a century of history, it is accompanied by the aerospace industry and developed new industries. Its development has withstood several ups and downs, this is because titanium and aircraft industry-related reasons. Overall, however, the speed of development of titanium is very fast, it is more than any other non-ferrous metals pace of development. This can be seen from the development of the world's titanium sponge industry: titanium sponge production scale of the 1960s 60kt / a, 70 years for 1lOkt / a, 80 years of 130kt / a, to 1992 has reached 140kt / a. Actual production in 1990 reached record levels, as 105kt / a. Currently, the world's titanium sponge production capacity of manufacturers and are listed in Table 1-1.
     After entering the 1990s, due to the reduced amount of titanium mesh and some Russian military and other countries to sell stocks of titanium sponge, so a few years ago a weak market. 1995 Titanium market began to rise, mainly due to a substantial increase in the amount of the civil B777 titanium and other civilian aircraft and golf clubs, titanium demand in 1996 reached a new high point. Experts predict that within the next few years the demand for titanium will continue to grow more substantial. At present, the main reason is to prevent the application of titanium expensive. It is expected that with the advancement of science and technology and titanium production process of continuous improvement, to expand production capacity and improve enterprise management level, to further reduce the cost of titanium products, is bound to open up a wider range of titanium market.
