Titanium can quickly react and gas

Liquid and solid titanium can not react, not combined with aqua regia could not reach it, however, titanium gas is very hit it off, like with nitrogen, oxygen, hydrogen, carbon dioxide, water vapor, methane and many other gases combined. This feature can produce titanium magical for us to use.
     You do not have more than one night to enjoy the colorful fireworks festival over it? Here there is a credit titanium. When combined with titanium powder and oxygen to burn quickly, and be able to produce a strong heat and glory. Fireworks can not only enhance the festive atmosphere at the festival, but also as a military flares, used to indicate the target or convey orders. In the arc lamp in the added amount of the grade 2 titanium forged ring compound, can increase its brightness. Using titanium strong absorption of air, the air can be removed, creating a vacuum. For example, the use of a vacuum pump made of powdered metal suppliers, you can put the air pumped only 1,000 million million. In the metallurgical industry, plus a small amount of titanium to steel or other metals, the "eat" inside the gas and impurities, can play a very good addition to the role of nitrogen deoxygenation, but also to eliminate the harmful effects of sulfur, thereby improving the steel and other alloy mechanical properties, to improve their resistance to corrosion.

Titanium more for aviation

Approximately 80% of titanium production for the aviation and aerospace industries. Airframe structural materials such as the US B-1 bomber, the titanium about 21%, mainly used in the manufacture of the fuselage, wings, skin, and bearing components. Airframe structural materials F-15 fighter, the titanium alloy with a capacity of 7000kg, accounting for about 34% of the weight of the structure. Boeing 757 aircraft structural parts, Powder coating titanium or about 5%, with a capacity of 3640 kg. McDonnell Douglas / production company DC10 aircraft alloy with a capacity 5500kg, accounting for more than 10% of the weight of the structure. The amount of Titanium round barin the chemical and general engineering areas: United States accounts for about 15% of its production in Europe accounts for about 40%. Due to the excellent corrosion resistance of titanium and its alloys, good mechanical properties, as well as qualified histocompatibility, making it a prosthetic device for the production of biological materials

Titanium is a new structural material

Titanium is a new structural material, it has excellent performance, such as low density (4.5gcm-3), high specific strength and fracture toughness, fatigue strength and resistance to crack growth, good low-temperature toughness, corrosion resistance excellent, the maximum operating temperature of some titanium alloys for 550 / C, is expected to reach 700 / C. So it gets increasingly widely used in aviation, aerospace, chemical, shipbuilding and other industrial sectors, is developing rapidly. Light alloy, steel, etc. (σ0.2 / density) versus temperature, stronger than the titanium alloy is higher than other light metals, steel and nickel alloys, and this advantage can be maintained to 500 / C or so, so some titanium suitable for manufacturing gas turbine components.

The production of titanium and titanium military profile

Titanium has many obvious superior characteristics: density (4.5kg / m3), high melting point (1660 ℃), corrosion resistance, high strength, good plasticity, but also through alloying and heat treatment methods to produce high mechanical properties the variety of alloys, is an ideal material for aerospace engineering structures. With a certain amount of oxygen, nitrogen, carbon, silicon, iron and other elements α phase titanium impurities. Stamping process with excellent performance, good weldability, and heat treatment is not sensitive to the type of tissue has a certain strength at a satisfactory plasticity conditions. Commercially pure titanium content of impurity elements in accordance with the division level. Its main strength depends on the content of oxygen interstitial elements, nitrogen. It has a high corrosion resistance in sea water, but poor in mineral acid. Generally used for manufacturing at a temperature -253 ~ 350 ℃ work discontinuity large variety of sheet metal parts or forgings, can also be manufactured rivets, wire and tubing. Application examples: Industrial use of commercially pure titanium in addition to manufacturing parts, extensive use of titanium alloy. It gets in the aviation, aerospace, chemical, shipbuilding and other industries increasingly wide range of applications, gas turbine component manufacturing, production of biological materials such as prosthetic devices. The density of titanium is generally about 4.5g / cm3, only 60% of steel, titanium's strength was close to the strength of ordinary steel, some high-strength titanium alloy structural strength than a lot of steel. Therefore, the ratio of titanium strength (strength / density) is much larger than other metal structures can be made out of high unit strength, rigidity, lightweight parts and components. At present, aircraft engine components, skeleton, skin, so the use of titanium fasteners and landing gear.

The use of titanium in the military industry, primarily titanium and titanium alloys have excellent performance based on: (1) reduce the structural quality, improve structural efficiency. Tactical and technical performance requirements of advanced aircraft structure has a relatively low quality factor (ie, the quality of the body structure / aircraft normal takeoff weight), low density powdered metal suppliers alloy, high strength, instead of structural steel and high temperature alloys, can greatly reduce the structural quality. Heat resistance (2) meet the temperature requirements of a titanium alloy. Currently hot strength titanium alloy by alloying the maximum temperature up to 500 ° C ~ 600 ° C, the temperature structure of the Titanium Flange Screwalloy also use up to 300 ° C ~ 400 ° C, the TI-64V can be used at 350 ° C under the long-term work, not at the high temperature of the plane (such as the rear fuselage, etc.) can be replaced by high-temperature performance does not meet the requirements of aluminum, TC11 long-term work at 500 ° C under the engine compressor components can be replaced by high-temperature alloys and stainless steel. (3) can be matched to the composite structure. To reduce the structural quality and meet the requirements of stealth, advanced aircraft extensive use of composite materials, the strength of titanium and composite materials, better match the stiffness, can get a good weight loss, and because both potential closer, easy to produce electricity Galvanic corrosion. (4) excellent in corrosion resistance. Titanium tube fittings is more excellent than other metallic materials and corrosion resistance in neutral oxidizing atmosphere and many harsh environments, small extent constrained by environmental conditions.

Application of titanium in military

Titanium is the end of the Second World War desire 1940s to 1950s began with the industrial production and gradually developed a high-performance structural materials is important. Since the first application is to provide high-performance materials for military aviation industry. With the development of national military industry, applications are continuously expanding titanium. So far, grade 2 titanium forged ring has been more and more applications in the aerospace, nuclear, ships, weapons and many other areas, has become an important strategic metal. Its application level has also become a country of advanced weaponry extent, reflects the level of a country's military and military strength, an important measure.

Brief history of titanium

The first discovery of titanium ore is a black sand called titanium iron sand, by Reverend William Gregor in Cornwall in 1791 found that the. He analyzed it and deduce the is composed of iron and an unknown metal oxides, and report to the Royal Geological Society of Cornwall.
In 1795, German scientists in Berlin Martin Heinrich Klaproth of Sch, called a RL red ore from Hungary. This is Jin Hongshi (TiO2) of a kind of form, but Klaproth realized it a previously unknown element oxides, he named titanium bar stock (Ti). When he was informed of the discovery of Gregor, he studied iserite and confirmed it also contains titanium tubing for sale. Until 1910, working in USA Ge M. A. Hunter to create a pure titanium metal, achieved by heating four titanium chloride and sodium metal.

The use of titanium (three)

The measure of a country's titanium industry scale has two important indicators: titanium sponge titanium production and yield, which reflects the Surgical Titanium Wire sponge production of raw materials production capacity, titanium production reflects the deep processing capacity. Sensor Titanium housing industry has formed China, America, CIS, Japan and Europe five production and consumption of the main. China titanium industry started in 1954, after the test, the industrialized production of fixed-point layout, application and technology progress gradually developed. Especially since twenty-first Century, the national demand, driven by the reform and open policy, the titanium industry in Chinese is make a spurt of progress. 2011 is the first year of China's "Twelfth Five Year Plan", in this year, China's titanium sponge and titanium processing material production continues to growth inertia. According to the China nonferrous metal industry association of titanium and zirconium hafnium branch of statistics, 14 domestic titanium sponge production enterprise total output in 2011 was 64952t, increased by 12.4% compared to the same period. According to the statistics of 30 enterprises, in 2011 China co production of titanium processing material 50962t, grow 33% compared to the same period.

The use of titanium (two)

Titanium and other elements of iron, aluminum, vanadium or Mo alloyed high strength, made of light alloy, has been widely applied in various aspects, including the space (jet engines, missiles and spacecraft), military, industrial processes (chemical and petroleum products, desalination of sea water and paper), automobile, agricultural products food, medicine (prosthetics, Department of orthopedics, transplantation and dental instruments and fillers), sporting goods, jewelry and mobile phone etc.. [4].
Two properties of titanium bar stock is most useful, corrosion resistance, strength and weight of the highest metal than [7]. In non alloy under the condition, the strength of titanium with some steel comparable, but lighter 45%[8]. There are two allotropes [9] and five kinds of natural isotopes, from Ti to Ti, the highest abundance was Ti (73.8%) [3] [10]. The chemical properties and physical properties of titanium and zirconium are similar, this is because the number of valence electrons of the two the same, and belong to the same family of elements in the periodic table.
In the earth's crust, titanium reserves second only to iron, aluminum, magnesium, ranking the fourth. Since Grade 9 Titanium components has high melting point, the proportion of small, high strength, good toughness, fatigue resistance, corrosion resistance, low thermal conductivity, high and low temperature tolerance performance is good, in cold and hot conditions, stress is small, its commercial value start was recognized in twentieth Century fifty years, should be used in high-tech field of aviation, space etc.. With the continuous chemical, petroleum, electric power, desalination, construction, daily necessities industry promotion, titanium metal are increasingly attention, known as the "modern metal" and "strategic metals", is an important strategic material and raise the level of national defense equipment indispensable.

The use of titanium (one)

Titanium is a chemical element, chemical symbol Ti, atomic number 22, is a transition metal silver, which features light weight, high strength, with metal luster, also have good corrosion resistance (including sea water, aqua regia and chlorine). Because of its stable chemical property, good resistance to high temperature, low temperature resistance, resistance to acid, alkali resistance, and high strength, low density, is known as "space metal" [2]. Titanium in 1791 by Gregor (William Gregor) in Cornwall and found that, by Klaproth (Martin Heinrich Klaproth) is named for its use in Greek mythology titan.
precision titanium products is considered to be a rare metal, which is due to the existence of a decentralized in nature and difficult to extract. But its relative abundance in all the elements in the tenth. [3] titanium ore mainly ilmenite and rutile, widely distributed in the crust and lithosphere. Titanium also exist in almost all organisms, rock, water and soil [4]. Remove the titanium need to use Kroll method [5] or the Hunter method from the main ore extraction. The most common compounds of titanium, Titanium round bar dioxide can be used in the manufacture of white pigment [6]. Other compounds also includes four titanium chloride (TiCl4) (as catalyst and used in the manufacture of smoke or air text) and titanium trichloride (TiCl3) (for the catalytic production of polypropylene).

The historical development of titanium (two)

In 1947, people began in the factory smelting titanium. That year, output was 2 tons. In 1955, the surge in production to 20000 tons. In 1972, the annual output reached 200000 tons. The yield strength of titanium are higher than steel, but it weighs almost only half the same volume of steel, Titanium Sheet Metal Price although slightly heavier than aluminum point, yield strength of it is 2 times larger than the aluminum. Titanium ratio strength higher than aluminum and steel, modulus and aluminum, steel is very close to the. In the universe of rocket and missile, a large number of titanium instead of iron. According to statistics, the world every year for the universe navigate titanium bar stock, has reached more than one thousand tons. Very fine titanium powder, or rocket good fuel, so ti is known as cosmic space metal, metal.
Titanium at elevated temperature easily and air reaction, but the high melting point of 1668 DEG C. At room temperature, titanium is not afraid of aqua regia and dilute nitric acid corrosion resistance, but not more than 5% acid corrosion and 7% hydrochloric acid corrosion. Titanium is not afraid of ambient seawater, someone had put a piece of titanium sank to the bottom of the sea, five years later to take up a see, above the sticky many small animal and marine plants, but not a bit rusty, still shining. People began to use titanium to titanium submarines -- manufacture of submarine. Since titanium is very strong, can bear high pressure, the submarine can sail at a depth of 4500 meters deep in the sea.

What is a titanium

Titanium is a chemical element, chemical symbol Ti, atomic number 22, in the chemical elements in the periodic table is located in the fourth period, the group IVB. Is a transition metal silver, which features light weight, high strength, with metal luster, resistance to wet chlorine corrosion.
Titanium Flange Screw is considered to be a rare metal, which is due to the existence of a decentralized in nature and difficult to extract. But its relatively abundant, ranking the tenth among all the elements. powdered metal suppliers ores are mainly ilmenite and rutile, widely distributed in the crust and lithosphere. Titanium is also present in almost all biological, rocks, water and soil. Remove the titanium need to use Kroll method or the Hunter method from the main ore extraction. The most common is a compound of titanium dioxide, can be used in the manufacture of white pigment. Other compounds also includes four titanium chloride (TiCl4) (as catalyst and used in the manufacture of smoke or air text) and titanium trichloride (TiCl3) (for the catalytic production of polypropylene).
