Provided is an aluminum alloy conductor used as a conductor for electric wiring, that maintains the same level of strength, elasticity, and conductivity as conventional products and has improved shock resistance and resistance to bending fatigue, even if used as ultrafine wire having a strand diameter of no more than 0.5 mm. This aluminum alloy conductor is characterized by having a chemical composition comprising: 0.10%-1.00% by mass Mg, 0.10%-1.00% by mass Si, 0.01%-1.40% by mass Fe, 0.000%-0.100% by mass Ti, 0.000%-0.030% by mass B, 0.00%-1.00% by mass Cu, 0.00%-0.50% by mass Ag, 0.00%-0.50% by mass Au, 0.00%-1.00% by mass Mn, 0.00%-1.00% by mass Cr, 0.00%-0.50% by mass Zr, 0.00%-0.50% by mass Hf, 0.00%-0.50% by mass V, 0.00%-0.50% by mass Sc, 0.00%-0.50% by mass Co, and 0.00%-0.50% by mass Ni, with the remainder being Al and unavoidable impurities. The aluminum alloy conductor is also characterized by a precipitate-free zone being present inside the particle grains and the width of the precipitate-free zone being no more than 100 nm. |
