Abstract

An 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. 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, 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 .
