ALUMINUM ALLOY MATERIAL, AND ELECTROCONDUCTIVE MEMBER, BATTERY MEMBER, FASTENING COMPONENT, SPRING COMPONENT AND STRUCTURAL COMPONENT USING SAME

It is an object of the present invention to provide an aluminum alloy material which can serve as a substitute for an iron-based or copper-based metal material, and has a high strength; and a conductive member, a battery member, a fastening component, a spring component, and a structural component including the aluminum alloy material. The aluminum alloy material has an alloy composition consisting of 0.2 to 1.8% by mass of Mg, 0.2 to 2.0% by mass of Si, 0.01 to 1.50% by mass of Fe, with the balance containing Al and inevitable impurities, wherein the aluminum alloy material has a fibriform metallographic structure where crystal grains extend so as to be aligned in one direction; and in a cross section parallel to the one direction, an average value of a size perpendicular to a longitudinal direction of the crystal grains is 270 nm or less.
