Abstract

An aluminum alloy material is an aluminum alloy material having 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, 0.06 to 2% by mass in total of at least one selected from Cu, Ag, Zn, Ni, Co, Au, Mn, Cr, V, Zr, and Sn, with the balance containing Al and inevitable impurities. The aluminum alloy material has a fibriform metallographic structure where crystal grains extend so as to be aligned in one direction. 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.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An aluminum alloy material comprising 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, 0.06 to 2% by mass in total of at least one selected from Cu, Ag, Zn, Ni, Co, Au, Mn, Cr, V, Zr, and Sn, 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.   
     
     
         2 . The aluminum alloy material according to  claim 1 , wherein an aspect ratio of the crystal grains is in excess of 10. 
     
     
         3 . The aluminum alloy material according to  claim 1 , wherein the aluminum alloy material has a Vickers hardness (HV) of 125 to 250. 
     
     
         4 . A conductive member comprising the aluminum alloy material according to  claim 1 . 
     
     
         5 . A battery member comprising the aluminum alloy material according to  claim 1 . 
     
     
         6 . A fastening component comprising the aluminum alloy material according to  claim 1 . 
     
     
         7 . A spring component comprising the aluminum alloy material according to  claim 1 . 
     
     
         8 . A structural component comprising the aluminum alloy material according to  claim 1 .
