  • Patent number: 11410787
    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.
