Titan have the system of Din, En
Titanium is a light silvery metal element of group IV of the periodic system D. I. Mendeleev, where indicated Ti. Opened in the end of XVIII century independently from each other Clarocom and Gregor. Titan is already dubbed the «metal of the future» for its extraordinary properties. High resistance and a significant ease in comparison with other metals, resistance to corrosion in aggressive environments, ease of forging, stamping, have made it an indispensable material of modern industry. Corrosion resistance is higher than that of noble metals, and an insignificant specific weight comparable to aluminum. The ductility of titanium is similar to copper and low creep — stainless steel. This metal is able to keep their properties from -250°C to the temperature of red hot steel. Exceptional durability, heat resistance, specific strength — brought him to the forefront of modern science and technology of the XXI century.

The main method is the restoration of TiCl4 at high temperatures with magnesium or sodium. Hot titanium readily absorbs atmospheric gases, therefore, the main objective of production technology is to minimize the contact of the hot melt with N2, O2, H2. The main drawback of the technology — energy-intensive process and high cost. Categorized titanium alloys according to the configuration of the crystal lattice; and the method of processing are divided into deformable and casting.
Titanium products are stored under cover or in covered warehouses, where there is reliable protection against various mechanical and other damage.
Titanium-based alloys are produced for the aviation and rocketry. Heat resistance, ease allow it to be used in production of thermal equipment. Since it retains high strength, ductility at very low temperatures, it is a very popular metal in cryogenic engineering. Of titanium alloys produced most of the important parts for shipbuilding — propellers and hull underwater vessels. The biological inertness allows you to create from it structural materials in reconstructive surgery, used in pharmaceutical and food industry. Titanium has become an indispensable material for surgical instruments, durable, lightweight prostheses. Its use almost unlimited — from the manufacture of bulletproof vests to modern interior design. Despite the high cost of this material, its use is economically justified durability and strength of the products.
