One of the most valuable metals on earth is copper.This is an excellent conductor of electricity and heat, which according to these parameters is second only to silver.A copper wire is almost the best material for filigree work.But above all it is used in industry as a conductor of electric current.Another copper wire has a high ductility.It is also relatively inexpensive and is very technical.It can be bent and cut, it is easy to give in to any kind of welding and soldering, copper wire drawing and rental available.Also it transcend both high and low temperatures (-200 to +250 degrees), and it does not work, atmospheric and soil moisture.Moreover, such a wire is virtually harmless and has a long service life.And because of these positive qualities are using it extensively.A
electrical copper wire is made from the same material grade not lower than the M1, and the chemical composition corresponds to GOST 859-2001.This metal is sufficiently high quality with a minimum content of impurities (about 0.1%).A cross-section of the M1 at the wire round.Yet it is annealed, and this increases its flexibility, and enables it to handle machining.A cold deformation gives it a high hardness.And for the electrical industry brands such wire used as M1 and M2P.And the additional letter "E" in their designation indicates that they require testing of the electrical conductivity.Also, depending on the hardness of the material it is still divided into hard and soft MM MT.This copper wire each of these brands has its own advantages and applications.And its purpose can be divided into electrical, wire for rivets and for low-temperature thermocouples.
A copper wire used in electric power, building, printing, machinery and light industry.Because it makes contact wires, cables, rivets, decorative elements and low temperature vapor.In the footwear industry it is made of small copper nails, hardware and studs.In industries such as mechanical engineering, telecommunications and shipbuilding, it is indispensable.Here it is used as windings for electric motors and transformers, draw conclusions from it spark plugs and fuses.Thus it is easy to work with, because it has a high ductility.Yet the resistance of copper wire is less than the made of aluminum, besides it stronger.Therefore, it is more profitable to do from the electric wire, for the same voltage and amperage required more lightweight and thin wire.
also copper wires and cable conductors clad metal such as nickel, which has its advantages over the tin and silver, especially in some industries use cable products.This is due to the fact that the copper wire coated with nickel, has a high resistance to corrosion and oxidation as well as to the effects of extreme temperatures.And it is mainly used in the manufacture of high-quality multi-core cables, which are designed for the aviation, electronics, aerospace, telecommunications and defense industries.Also, copper-nickel wire is made high temperature cables, terminals and spark ignition fuses.It can withstand temperatures ranging up to 750 degrees.
