Copper Wire

Copper wire remains extremely popular in the supply of electricity. Copper can be easily manipulated into wire form and because of both its thermal and electrical conductivity, it is routinely used in all kinds of electronics. Only silver is more conductive which is why copper is the affordable material of choice. According to scientific research, a 4-inch thick bar of copper can be heated and stretched into a wire over 2,000 km long and thinner than a human hair. Its versatility is practically limitless. It is used in the generation and transmission of power, the distribution of power for telecommunications networks, electronics circuitry and the manufacture of electrical contacts.
