Aluminum alloy wire welcomes new breakthroughs, new materials inject new vitality into green development

The research and application of new materials are of great significance for promoting social progress, and with the rapid development of industry, the importance of new materials is constantly increasing. Among them, aluminum alloy wire, as a lightweight, high-strength, and excellent conductive material, is increasingly widely used in fields such as power and new energy. Recently, Kunming University of Science and Technology has made significant breakthroughs in the research and development of high-performance aluminum alloy wires, providing a broader space for the future development of aluminum alloy wires.

Aluminum alloy wires have broad application prospects in fields such as power transmission and new energy generation due to their lightweight, high strength, and good conductivity. In the transmission scenario, aluminum wires are lighter than copper wires, which can reduce the cost of transmission lines and the load on power towers, especially suitable for long-distance and high current transmission. In addition, aluminum wires are widely used in various transformers, distribution boxes, and other equipment in power distribution scenarios, which not only reduces costs but also reduces space and weight. These advantages also make it have great potential in new energy fields such as wind power generation and solar photovoltaics.

However, there is a constraint relationship between the conductivity, strength, and heat resistance of materials, which results in the conductivity of heat-resistant aluminum alloy wires being limited to around 60%, and the strength of 4mm diameter wires is usually around 160 megapascals. Aluminum wires cannot fully demonstrate their theoretical strength.

Kunming University of Science and Technology is attempting to achieve technological breakthroughs to address this issue. The school has collaborated with multiple domestic institutions to refine alloy grains through continuous casting and rolling, analyze the aging effect of zirconium atoms, and strengthen through cold drawing deformation. It has successfully increased the strength of heat-resistant aluminum alloy wires to 195 ± 2 megapascals while maintaining their conductivity at 61.1%, breaking the performance record for heat-resistant aluminum alloy wires under industrial production conditions.

The relevant research results have been published in the excellent journal "Materials Research Communication" in the field of materials science and metallurgical engineering in China. At the same time, from a long-term perspective, this achievement not only enhances China's position in the international materials science field, but also provides strong support for the development of related industries in China. Especially in the field of new energy, high-performance aluminum alloy wires will better meet the demand for wire materials in new energy power generation equipment and promote the rapid development of the new energy industry.

Believing in the future, with the continuous advancement of technology and the expansion of the market, high-performance aluminum alloy wires will be applied in different fields, helping green development and making greater contributions to China's economic and social development, injecting new impetus into China's technology industry.
