China's copper resources are problematic and have scarce resources. The recoverable reserves are about 30 million tons, accounting for only 4.5% of the world. In 2015, China's copper consumption exceeded 11.5 million tons, accounting for more than 40% of the world. In addition, since 2010, China's copper The dependence on resource imports is as high as 75%.
Therefore, the development of copper-aluminum composite materials will help reduce costs and increase efficiency, and promote the healthy development of the industry to promote aluminum-clad copper. First, instead of pure copper flat platoons, China's annual demand for flat platoons is about 1 million tons, including 400,000 tons in the power industry, 400,000 tons in the construction sector, and 200,000 tons in the fields of metallurgy, chemicals, transportation, and manufacturing.
More than 90% can be replaced by copper-clad aluminum composite flat row. In addition, in the high-tech field, the demand for cost reduction and weight reduction is also extremely strong. The copper-clad aluminum composite flat row is used in new energy (wind power, photovoltaic) and other fields, which helps to reduce costs and enhance the competitiveness of strategic emerging industries; It is used in modern transportation fields such as high-speed rail and large airplanes, which is conducive to weight reduction and energy consumption.
Take Airbus A380 passenger aircraft as an example. Each frame uses 1 ton of copper-clad aluminum composite flat row, which can reduce weight by 1.2 tons, and the effect is remarkable; It is an alternative to pure copper flat wire. China's cable and electromagnetic flat wire are currently used at an annual consumption of about 3.5 million tons, and the replacement capacity is about 1 million tons. If copper-clad aluminum is used instead of pure copper, it will greatly reduce the winding, wiring and transportation weight. Moreover, large-size cables, large-scale power transformers, and special transformer winding wires can be replaced by copper-clad aluminum. Xinyu as an expert enameled wire manufacturer in China, we must take the responsibility and make technology development in Enameled Wire industry.
