Abstract:
1. An aluminum alloy conductor, consisting essentially of: 0.01to 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 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 within the range of 0.1 μm or more but 2 μm or less and is selected from the group consisting of Al—Fe, Al—Fe—Si, Al—Fe—Si—Cu, and Al—Zr, the intermetallic compound B has a particle size within the range of 0.03 μm or more but less than 0.1 μm and is selected from the group consisting of Al—Fe—Si, Al—Fe—Si—Cu, and Al—Zr, the intermetallic compound C has a particle size within the range 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 the relationships of 0.1%≦a ≦2.5%, 0.1% ≦b ≦3%, and 1%≦c≦10%, respectively, wherein the aluminum alloy conductor has a recrystallized microstructure.
