The invention discloses a low-resistivity high-strength aluminum alloy conductive tube. The low-resistivity high-strength aluminum alloy conductive tube comprises, by mass, 0.50% -0.55% of Si, 0.15% of Fe, 0.01% of Cu, 0.01% of Mn, 0.52%-0.58% of Mg, 0.01% of Cr, 0.01% of Zn, 0.02% of Ti, not greater than 0.05% of Zr, not greater than 0.05% of mixed rare earth Re, less than 0.01% of Pb, not greater than 0.05% of B, not greater than 0.05% of V and the balance Al, wherein the total content of Zr, Re, Pb, B and V is less than or equal to 0.15%; and when the total content of Mn, V, Cr and Ti is lower than 0.012%, the addition amount of B is 0; and when the total content of Mn, V, Cr and Ti exceeds 0.012%, the addition amount of B is 1.25-1.5 times the stoichiometric number of B needed by a boron compound formed by Mn, V, Cr, Ti and B. According to the low-resistivity high-strength aluminum alloy conductive tube, the content of magnesium and silicon is strictly controlled, the content of other impurity elements is reduced, and the conductivity and performance of the tube are improved through standard limitation of the subsequent extrusion, quenching, stretching, aging and other processes.
