Title:
ALUMINIUM ALLOY MATERIAL, AND CABLE, ELECTRIC WIRE, AND SPRING MEMBER USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/131053
Kind Code:
A1
Abstract:
The present invention provides an aluminium 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 aluminium alloy material has a fibrous metal structure in which crystal grains extend in one direction. In a section of the aluminium 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 aluminium alloy material from the surface of the aluminium 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 aluminium alloy material to the average crystal particle size R1, R2/R1, is 1.8 or higher.
