摘要： An aluminum alloy material which has high yield strength and excellent electric and thermal conductivity and can have a constant break elongation even when the aluminum alloy material has a small diameter. The aluminum alloy material has an alloy composition including 0.05 to 1.50 mass % of Fe, at least one of 0.01 to 0.15 mass % of Si, 0.01 to 0.30 mass % of Cu and 0.01 to 1.50 mass % of Mg, and a remainder made up by Al and unavoidable impurities, and has a fibrous metallic structure in which a plurality of crystal grains extend in line in one direction. The average value of maximum dimensions of the plurality of crystal grains in a direction perpendicular 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 maximum dimension in a direction perpendicular 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.

摘要： A window includes a base region and a compressive stress region disposed on the base region. The compressive stress region includes Li+, Na+, and K+ ions. The compressive stress region includes a first compressive stress portion in which a concentration of the K+ ions decreases, a concentration of Na+ ions increases, and a concentration of the Li+ ions increases, from a surface of the window toward the base region. A second compressive stress portion is adjacent to the first compressive stress portion. In the second compressive stress portion, the concentration of the Na+ ion decreases and the concentration of the Li+ ion increases, from the first compressive stress portion toward the base region. The window thereby has a high surface compressive stress value and impact resistance.
