<p>{Problems} To providing an aluminum alloy conductor, which has sufficient electrical conductivity and tensile strength, and which is excellent in workability, flexibility, resistance to bending fatigue, and the like. {Means to solve} An aluminum alloy conductor, containing: 0.01 to 0.4 mass% of Fe, 0.1 to 0.3 mass% of Mg, 0.04 to 0.3 mass% of Si, and 0.1 to 0.5 mass% of Cu, and further containing 0.001 to 0.01 mass% of Ti and V in total, with the balance being Al and inevitable impurities,
wherein the conductor contains three kinds of intermetallic compounds A, B, and C, in which the intermetallic compound A has a particle size of 0.1 µm or more but 2 µm or less, the intermetallic compound B has a particle size of 0.03 µm or more but less than 0.1 µm, the intermetallic compound C has a particle size of 0.001 µm or more but less than 0.03 µm, and
an area ratio a of the intermetallic compound A, an area ratio b of the intermetallic compound B, and an area ratio c of the intermetallic compound C, in an arbitrary region in the conductor, satisfy: 0.1% ‰¤ a ‰¤ 2.5%, 0.1% ‰¤ b ‰¤ 3%, and 1% ‰¤ c ‰¤ 10%, respectively.</p> |
