Titanium, titanium products
This element was discovered in 1789, but for a long time it was thought due to impurities is little robust and never been used. Received in 1925, the pure titanium proved to be very practical metal with many valuable properties. Engineers and designers immediately found a use for it.
Titan is endowed with low density, high specific strength, very high resistance to corrosion, does not lose strength at extreme temperatures. It became the basis of rocket and modern aviation. Light and durable titanium alloys retain their quality at temperatures up to 500 °C, when aluminium or magnesium alloys are already not working, and steel and Nickel alloys are inferior to them in specific strength.
Thanks to its resistance to corrosion, titanium has broad applications in the chemical industry. However, it should be noted that the process of welding is difficult due to the propensity to oxidize readily in hot. When welding must be protected from exposure to atmospheric gases not only melted the edge of the seam, but the whole of the heated metal. Now successfully used arc welding in argon atmosphere, electron beam welding and contact welding methods.
Titanium alloys, as is known, was first used in the creation of jet engines, which reduced their weight by 15…20%. In particular, it also produce spare parts of compressor, parts of guide vane and all kinds of fasteners. Today’s market can offer titanium and titanium raw materials at quite decent prices, though the price of titanium mill products was extremely high. He has a rare combination of characteristics:
in comparison with aluminum in a conventional aircraft;
— as a material for supersonic aircraft, compared with chromium-Nickel alloys.
Hull structures of titanium allow to create unique underwater court. Titanium is a metal that facilitates a specific gravity of any product. In modern aircraft, missile, shipbuilding production — it is the case, parts of wings, engines, which is the optimal solution to replace the unworkable in areas such metals.
Titanium is a lightweight, silvery metal element No. 22 of group IV of the periodic system. Opened in the end of XVIII century independently from each other an Englishman, William Gregor, and the German chemist Clarocom. Already at that time Titan dubbed «the metal of the future», so extraordinary qualities he possessed. Its strength is like the strength of Damascus steel, it is much lighter than other metals, resistant to corrosion and action of aggressive media, easily forged and stamped. Its corrosion resistance is higher than that of alloys of noble metals, and low specific weight comparable to aluminum. Low creep of titanium is similar to stainless steel, and the elongation and ductility — level indicators copper. It retains its quality from -250°C to t° red heat steel. Exceptional specific strength, durability, resistance to heat — made it an indispensable material on the cutting edge of science and technology of the XXI century.

The primary method of obtaining titanium — restoration of TiCl4 at high temperatures with sodium or magnesium. Hot titanium reacts easily with atmospheric gases, so the main purpose of production technologies is to minimize the contact of hot metal with N2, O2, H2. The main drawback is the high cost and energy consumption of the process. In metallurgy titanium alloys are classified according to the configuration of crystal lattices: β-state (in the form of a cube), α-state (in the form of a hexahedron) and α+β (mixed state). According to the method of processing the alloys are divided into casting and wrought.
|Titanium mill products||Diameter, mm||Length, mm||Width, mm|
|Pipe||12 — 300||1000−5000||0.5−6|
Note: pipe weight up to 200 kg
Titanium mill products are stored in covered warehouses or under the shed providing adequate protection against mechanical and other damage.
Based on titanium to produce alloys for rocket and aircraft industry. Lightness and heat resistance of titanium will be used in the manufacture of heating equipment. He is in demand in the cryogenic industry, because it retains high ductility and toughness in extreme cold. From titanium alloys produce the most important parts for shipbuilding, including hull and propellers underwater vessels. Its biological inertness allows you to create structural materials for reconstructive surgery and use in the food and pharmaceutical industry. The inertia of Titan is important to create surgical tools and implants in orthopedics, dentistry. Titanium produce body armor and modern design elements. Despite the high price, its use is economically justified lightness, strength, durability.
