Description

technical field [0001] The invention relates to the technical field of conductive tubes, in particular to a high-conductivity and high-hardness conductive tube. Background technique [0002] Aluminum has excellent electrical and thermal conductivity, its electrical conductivity is second only to silver and copper, and its electrical conductivity is about 62% of that of copper. In order to save the amount of copper, in the field of electric power and electrical industry, it has become a development trend to use aluminum instead of copper to make wires, cables, conductive components and other products. The main material of the aluminum alloy conductive tube is Al-Mg-Si alloy. The 6000 series aluminum alloy is widely used in the automobile, electric power and electrical industries due to its moderate strength, good plasticity, corrosion resistance and excellent conductivity. Among them, 6063 aluminum alloy can be widely used as the main material in the production of conductive...
