WIPO Patent Application WO/2018/012482

A1

The purpose of the invention is to provide: a high-strength aluminum alloy material that has excellent heat resistance and that can serve as a substitute for an iron-based or copper-based metal material; and an electroconductive member, a battery member, a fastening component, a spring component and a structural component using said aluminum alloy material. Disclosed is an aluminum alloy material comprising an alloy composition including 0.2-1.8 mass% Mg, 0.2-2.0 mass% Si, 0.01-1.50 mass% Fe and 0.06-2 mass% in total of at least one element selected from Cu, Ag, Zn, Ni, Co, Au, Mn, Cr, V, Zr and Sn, with the remainder comprising Al and inevitable impurities, wherein: the crystal grains have a fibriform metallographic structure extending so as to be aligned in one direction; and, in a cross section parallel to said one direction, the average value of the dimension perpendicular to the length direction of the crystal grains is 270 nm or less.
