Preparation method of ultra-high strength and high-conductivity industrial pure aluminum thin wire

This invention relates to the field of aluminum conductor wire research, specifically to a method for preparing ultra-high strength, high conductivity industrial pure aluminum fine wire. Pure aluminum ingots are sequentially subjected to forging, rolling, primary drawing, low-temperature annealing, and secondary drawing to obtain ultra-high strength, high conductivity industrial pure aluminum fine wire. This invention improves the strength of aluminum wire by controlling the grain size without changing the composition. This is mainly achieved through a process of two drawing stages, with low-temperature annealing performed between the primary and secondary drawing stages. This refines the radial grain size within the pure aluminum fine wire, thus increasing its strength. Compared to existing pure aluminum wires, the strength is significantly improved while maintaining the same conductivity, enhancing the service safety of the aluminum wire. Furthermore, this invention requires no additional alloying elements, resulting in significant advantages in low additional costs. The simple operation process facilitates industrial application.
