Problems solved by technology

When a 9~10mm rod is drawn into a 1~3mm filament, it is easy to break, and the joint is required after the break, and the resistance at the joint becomes larger, which affects the use after becoming a cable; at the same time, the diameter of the easily drawn filament is not large. Uniform, affects the distribution of the current

Description

Technical field [0001] The invention relates to the technical field of cable conductor processing, in particular to a method for preparing an aluminum alloy rod. Background technique [0002] Alloy conductor is an emerging conductor material formed by adding rare earth, magnesium, copper, iron and other elements to pure aluminum. The main material is rare earth and AA8000 (Al-Mg-Cu-Fe aluminum-magnesium-copper-iron alloy) conductor material, which is a soft aluminum alloy used in power distribution lines. Among them, copper can increase the resistance stability of the alloy at high temperature; iron can increase the creep resistance and compaction of the conductor by 280%, avoiding the relaxation problem caused by creep; magnesium can improve the creep resistance and compactness of the conductor at the same interface pressure. The contact point has higher tensile strength; rare earth can improve the mechanical properties of the alloy, increase the electrical conductivity of the ...
