Document Type and Number:
WIPO Patent Application WO/2020/158682
Kind Code:
A1
Abstract:
Provided is an aluminum alloy material which has high proof stress and excellent electric and thermal conductivity and can have a constant breaking elongation even when the aluminum alloy material has a small diameter. The aluminum alloy material according to the present invention is characterized by having an alloy composition comprising 0.05 to 1.50% by mass of Fe, at least one of 0.01 to 0.15% by mass of Si, 0.01 to 0.30% by mass of Cu and 0.01 to 1.50% by mass of Mg, and a remainder made up by Al and unavoidable impurities, and also having a fibrous metallic structure in which a plurality of crystal grains extend in line in one direction, wherein the average value of largest dimensions of the plurality of crystal grains in a direction orthogonal to the length direction is 800 nm or less in a cross section parallel to the aforementioned one direction, and there is no specific void of which the largest dimension in a direction orthogonal to the length direction is 1.0 μm or more as observed at a center part of the cross section in the thickness direction or the abundance of the specific voids is 10 or less per 10000 μm2.
