Copper is one of the most ancient materials and one of the most extensively used non-ferrous metals nowadays. Copper, like Ag and Au, is a part of the first row transition series of elements, which includes Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn. It is found in group 11 of the periodic table. The element has an atomic number of 29, a mass of 63, two primary oxidation states (+1 and +2), and two naturally occurring isotopes (63Cu and 65Cu) with 69.17 percent and 30.83 percent abundances, respectively. Copper is easy to stretch, mould, and shape, is corrosion-resistant, and conducts heat and electricity well. Copper was crucial to early humans as a result, and it is still used in a range of home, industrial, and high-tech uses today.
Copper wire is used in the winding of motors and transformers. Copper wire comes in a variety of gauges (32 gauge to 18 gauge). The copper wire gauge is determined by the winding required for the particular motor or transformer. For submersible motor winding, wire with a conductor diameter of 0.500 to 4.000 mm is appropriate. Copper wire is in high demand among motor and transformer manufacturers, and it is also utilised in the rewinding of motors and transformers.
Copper wire is utilised in a wide range of applications, including power generation, transmission, distribution, telecommunications, electronics circuitry, and a wide range of electrical equipment. Electrical connections are also made of copper and copper alloys. The copper industry's most important market is building electrical wire.
Copper is mostly utilised in the electrical sector for parts of electrical apparatus, bus bars, and wire, among other things. Copper is not very ductile at temperatures between 250 and 600°C, and because to its extreme brittleness, it cannot be forged or stamped at temperatures exceeding 800°C. Only its alloys bronze and brass are commonly forged or stamped, and pure copper is rarely forged or stamped.
The expanding demand for power, light, and communication has kept cables and wires, which account for nearly 40% of India's electrical industry, in high demand. Wires and cables are used extensively in a variety of industries and play an important part in every element of infrastructure development. The growth of the manufacturing industry and infrastructure in the electricity, telecommunications, residential, and commercial sectors is closely related to the demand for wire and cables. As a result, the government's initiatives on several fronts, including as power, housing, infrastructure, and digitization, will almost certainly produce a lot of business for the wire and cable industry in the near future.
