The copper circle has high resistance to corrosion under the influence of moisture, high electrical and thermal conductivity. It is cheap to manufacture, durable, reliable, works in a wide range of temperatures. It is easy to cut, drill, solder, weld, it is high-tech, easy to install, has an aesthetic appearance, and can be reused after disposal. All this explains its high demand in various production industries. Compared to a steel circle, a copper one is less durable, but much lighter and more plastic. Alloys M1, M1r, M2, M2r, M3, M3r (chemical composition according to GOST 859) are used for the production of copper circles.(//tractor-service.com)
Copper circle is used in electrical engineering and instrumentation for the manufacture of components and structural parts, as well as in metallurgy, metalworking, mechanical engineering, and shipbuilding due to its resistance to corrosion. It is often used for the production of conductive structures and housing parts. Bolts, screws, various accessories, spindles, shafts, valves, parts of mechanisms for gas and water systems are made from it.
