Copper-aluminum composite belt is made of copper and aluminum through copper-aluminum composite technology. Therefore, copper-aluminum composite belt has both the aesthetics of copper and the corrosion resistance and low cost of aluminum. It is widely used in electronics, automobiles, energy, electrical appliances, petrochemicals, metallurgy, machinery and other industrial fields. As we all know, China is a country with more aluminum and less copper. It is faced with the problem of overcapacity in the aluminum industry and the shortage of copper resources. In industrial production, at least 60% of copper raw materials rely on imports. In order to solve the problem of lack of copper resources in industry, copper-aluminum composite belts that can replace copper metal have emerged. The use of copper-aluminum composite belts is of great significance to alleviate the situation of more aluminum and less copper in my country and resolve the overcapacity of the aluminum industry.

After years of development, my country's copper-aluminum composite belt industry has made great achievements and has become one of the world's major producers and exporters of copper-aluminum composite belts. The production level, product quality, and economic benefits of copper-aluminum composite belts in our country have been greatly improved, and the goal of modern industry has been gradually achieved.
The upstream of copper-aluminum composite belts is mainly copper and aluminum. Copper-aluminum composite materials are mainly composed of aluminum core and copper cladding. Copper has excellent conductivity and good corrosion resistance, and aluminum has low cost and light weight. When used for high-frequency wires and high-current conductive bars, the conductivity is almost the same as that of pure copper conductors.
The downstream industries of copper-aluminum composite belts are mainly electronics, automobiles, energy, electrical appliances, petrochemicals, metallurgy, machinery and other industrial fields. Copper-aluminum composite materials are a new type of layered composite materials developed in the power and industrial electrical appliance industries in recent years. It is a high-performance composite conductor.
In recent years, Chinese steel companies have continuously enhanced their innovation awareness and increased their investment in scientific research on copper-aluminum composite materials, but there is still a gap compared with some international steel companies. The independence, synergy, systematicity, stability and continuity of technological innovation in the steel industry are still insufficient, and the supply of technology still cannot fully meet the development needs of the industry. Some core technologies have not been mastered, and the role of key core technology followers has not been shaken off. Although the localization rate of large-scale metallurgical equipment can reach more than 90%, key and core technologies still rely on imports. Therefore, for a long time in the future, Chinese steel companies still need to enhance their innovation awareness, strengthen their innovation systems and mechanisms, increase R&D investment, and enhance their innovation capabilities.
