Copper wire is the billet used by copper wire manufacturers to produce wire, cable, enameled wire and electronic wire. Bare copper wire is a new substitute material for bare copper wire and tinned copper wire. It has the characteristics of light weight, high strength, corrosion resistance and low price. It can be used as the ideal conductor and shielding material for communication cables, signal cables and shielding cables. Coaxial cables and data transmission cables do not affect the test data. Copper wire is one of the important basic materials in electronic, electrical and communication industries. Copper and copper alloy materials are widely used in electronic, electrical and other fields due to their excellent electrical conductivity, thermal conductivity and processing plasticity. Communication and other areas. With the rapid and stable development of the world electronic communication industry, copper wire manufacturers to wire and cable, enameled wire and electronic wire industry copper wire demand is also growing rapidly, its upstream products copper wire demand is also increasing. It's also increasing. Quality requirements are also getting higher and higher. From the development history and present situation of the world copper wire, the production and consumption of wire are balanced on the whole, and the main consumer market of wire is also the main consumer of wire. The main consumption market of wire is western developed country, copper wire consumption is in the world forefront. The United States is currently the world's largest consumer of power lines, followed by Japan and Germany. According to relevant data, copper wire consumption in 2000 was 253,104 tons in the United States, 88,104 tons in Japan, and 63,104 tons in Germany. The development of world electronic industry, electric industry and communication industry has greatly promoted the development of copper processing industry. At present, 60% of the world's copper production is used in conductor production. Although copper wires are influenced by aluminum and optical fibers, they still have a large market in many fields (e.g. low voltage wires, equipment, instruments and motors) and are still expanding into new applications. So far, the number of copper conductors has increased. According to concerned branch statistics, international market needs all sorts of enameled wire every year, among them Japan 40,104 tons, the United States 60,104 tons. The market demand is 30 million kilometers. There are more than 13 million kilometers of low-voltage wired telephone lines. Kilometer and cable cable demand exceeds 1.4 million kilometers. . It can be seen that in the international market, copper wire manufacturers on copper wire demand is very large.
