Wire copper
The wire is copper round electrotechnical
MM (A) - a wire copper annealed
MT (R) - a wire copper neotozhenny
Scope
The copper wire is a wire which found broad application thanks to the properties. Thanks to the conduction properties the copper wire is applied in such branches as mechanical engineering, telecommunications, power industry, etc. Advantages of a copper wire it is plasticity, high heat conductivity, resistance to corrosion, durability.
Copper is one of optimal variants for production of electric conducting. As the conductor for electric energy is used a copper wire with a diameter up to 8 mm. She is tinned and at her can be present or not a sheeting. In electrotechnical a copper wire of 99,99% of copper. Wires, cords, a cable, windings for engines, etc. are made of a copper wire. There are several types of a copper wire on application: for rivets, for the electrovacuum industry, electrotechnical, welding.
