Abstract: The present invention provides an aluminum alloy material which has high resistance to flexural fatigue and prescribed elongation characteristics; contains, in terms of mass %, 0.20-1.80% Mg, 0.20-2.00% Si, and 0.01-1.50% Fe; and further contains at least one element selected from among Cu, Ag, Zn, Ni, Ti, Co, Au, Mn, Cr, V, Zr, and Sn in a total amount of 0.00-2.00%, with the remainder made up of Al and inevitable impurities. The aluminum alloy material has a fibrous metal structure in which crystal grains extend in one direction. In a section of the aluminum alloy material perpendicular to the longitudinal direction of the crystal grains, the average crystal particle size R1 of the crystal grains present at a position D, which is a position at a depth of 1/20 of the thickness of the aluminum alloy material from the surface of the aluminum alloy material, is 400 nm or less, and the ratio of the average crystal particle size R2 of the crystal grains present at a central position in the thickness direction of the aluminum alloy material to the average crystal particle size R1, R2/R1, is 1.8 or higher.

Abstract: The present invention provides a movable cable, which has strength that is at least equal to conventional movable cables while having excellent flexural fatigue resistance and flexibility as well as being lightweight. This movable cable 10 has an electric conductor therein. The conductor comprises a first conductor 2 made of a specific aluminum alloy material wherein: the alloy composition contains, in mass %, 0.05-1.8% Mg, 0.01-2.0% Si, 0.01-1.5% Fe, and at least a total of 0.00-2.00° of one element selected from the group consisting of Cu, Ag, Zn, Ni, Co, Au, Mn, Cr, V, Zr, Ti and Sn, the balance being Al and unavoidable impurities; the crystal grains have a fiber-like metal structure in which the crystal grains all extend in one direction; and in a cross-section parallel to the one direction, the average crystal grain dimension perpendicular to the longitudinal direction is 400 nm or less. The ratio X of the area of the first conductor 2 in the whole conductor of the movable cable 10 is in the range of 10-100%.
