Problems solved by technology

[0002] Because copper alloy has many excellent properties, it has a wide range of uses in the national economy, such as machinery, electronics, automobiles, electric power, communications, transportation and light industry. The consumption of copper wire is very large. In 2009, my country The statistical production capacity of copper wire is 790,000 tons, the actual production capacity is 570,000 tons, and the capacity utilization rate is not high. The conductivity and strength of copper wires in the existing technology are difficult to reach high standards at the same time, and the weather resistance is poor.
