Copper wire has high ductility, thermal and electrical conductivity, resistance to atmospheric and soil moisture and temperature extremes from --200 ° C to + 250 ° C. It is cheap, very technological, easily cut, bends, is available rolling, drawing, any type of soldering and welding. After utilization of copper is typically recycled. Ease of installation, aesthetic appearance, durability and harmlessness make this wire only beneficial to use.
Copper plastic, but soft, its strength is low when compared with steel.

Produce copper wire on a continuous casting-rolling mills of the M1 and M2 alloys containing copper, respectively, 99.9% and 99.7%. Chem. It normalizes the composition of GOST 859−2001. Preparation and sampling for the monitoring of the composition is carried out in accordance with GOST 24 231−80. Produced copper wire for rivets in accordance with TU 48−21−456−2006; for low-temperature thermocouples — 22 according to GOST 666−77; Electrical round — TU 16−705.492−2005. All long products has normal precision manufacturing, clean surface without discoloration with the usual quality finishes. The electrical resistance of the wire (measured in Omxmm 2 / m) at 20 ° C shall not exceed the following values:
— To mark MM: 0.1 724;
— The brand MT up to Ø 2.44 mm: 0.1 780;
— The brand MT Ø more than 2.44 mm 770 0.1.
For plating copper conductors of cables used nickel. This wire is resistant to the action of extreme high and low temperatures, oxidation and corrosion. Because it produces high-quality multi-core cables in the aviation, aerospace, telecommunications industry, defense industry. It is used for the production of fuses and terminals spark ignition. Nickel-plated copper wire can withstand temperatures up to 750 ° C. Annually in the world more than 11 000 metric tons of copper wire clad with nickel or silver.
M1 grade wire made soft and hard, each of which is characterized by certain qualities and scope. The marking indicates the purity of the alloy. M1 — circular cross section of primary copper wire of 99.9% purity. The content of impurities in it does not exceed 0.1%, which optimizes its performance. In the notation marks M1, M1P, designed for the electrical industry, and be tested on the electrical conductivity include an additional «E» letter. Through annealing increases the plasticity and workability of the material cutting, and provides sufficient strength cold deformation.

Electrical engineering, mechanical engineering, construction, light industry and printing. Copper wire is indispensable in the production of the contact wires, cables, rivets and low-temperature thermocouples. It is relevant in the manufacture of cables, it is stronger aluminum, and its electrical resistance is less, that allows the use of thinner copper wires with the same amperage and voltage. It is used in the textile and footwear industry, for example, for the production of copper nails and pins, accessories, decorative items ,. It is relevant in telecommunication networks, shipbuilding and mechanical engineering. It is used for the production of windings of transformers and electric motors, the conclusions of the spark plugs, fuses and so on. N. The plasticity of copper wire, its easy soldering greatly simplifies the installation of electrical circuits.
