Method for the Production of an Aluminum Alloy Sheet that Exhibits Excellent Surface Quality After Anodizing |
摘要 |
<p>An aluminum alloy sheet exhibits excellent surface quality after anodizing without showing a band-like streak pattern. The aluminum alloy sheet is a 5000 series aluminum alloy sheet that includes 1.0 to 6.0 mass% of Mg, wherein the concentration of Mg in a solid-solution state that is present in an outermost surface area of the aluminum alloy sheet varies in the widthwise direction of the aluminum alloy sheet in the form of a band having a width of 0.05 mm or more, and the difference in the concentration of Mg between adjacent bands is 0.20 mass% or less.</p> |
