Sheet, strip, foil

dignity

Due to the high technological and operating characteristics, sheet and strip of niobium are widely used by industries where the production process involves high temperatures and corrosive environments. Niobium is a heat-resistant and at the same time very flexible, durable material, designed to work at t° above 1500 °C under load. Pure niobium may be laminated in a thin tape with a thickness of 10 µm. Sheet and strip of niobium have the highest strength and corrosion resistance. This is not only one of the most refractory metal (t° melting point 2468 °C, t° boiling point 4742°C), it is the basis of high-temperature, chemically resistant and superconducting alloys are used in metallurgical equipment, industrial chemistry, Metalworking. This is a relatively heavy metal, the density of 8.57 g/cm3, it is 2 times heavier than titanium, but more than 2 times lighter than tungsten. For nuclear power are important as niobium — narrow capture cross section for thermal neutrons and the induced radiation is minimal. Electrical — low work function of electrons. Qualities such as excellent machinability hot and cold, good weldability, make the valuable niobium structural material. The most important field of its use of space and aviation technology, military-industrial complex.

disadvantages

This multiple element of the earth’s crust. Mining and production it is associated with a number of difficulties. This is a fairly expensive metal. The niobium powder has a high Flammability. If contact with skin or mucous membranes of niobium dust causes irritation. MPC NB = 0.01 mg/l. the Penetration of niobium inside the body causes severe damage to the nervous tissue up to paralysis.

use

Heat-resistant niobium necessary for the production of parts of the jet and space technology. For the needs of nuclear energy important minimal induced radioactivity of niobium. Sheet and strip of niobium are the basis of responsible fragments of nuclear installations, in particular equipment for circulation of liquid metal coolants in atomic reactors. From niobium sheet manufacture containers for storage of radioactive waste and fuel element sheath. Low work function of electrons important in the manufacture of high-power electronic devices, generators, condensers, etc., Chemical resistance of the wire and the circle of niobium is widely used to manufacture corrosion-resistant parts for the processing and the pulp and paper industry. Superconducting qualities of this metal found use in cryotron components of computers.

quality requirements

Rental valid insignificant defects, the risks, the traces of broach, shrinkage irregularities, which fall within the boundaries specified by the standard deviations. On the cut samples must not contain foreign inclusions. The surface must be clean, free of cracks, burrs. Rolled in original packaging stored in closed warehouses. It can be transported by any transport. When transporting the sheet and strip shall be protected from mechanical damage, moisture, dirt, aggressive chemicals.
