Aluminum alloy sheet that exhibits excellent surface quality after anodizing and method for producing the same |
摘要 |
An aluminum alloy sheet that exhibits excellent surface quality after anodizing, includes a peritectic element that undergoes a peritectic reaction with at least aluminum, and requires an anodic oxide coating is characterized in that the concentration of the peritectic element in a solid-solution state that is present in the 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 less, and the difference in the concentration of the peritectic element between adjacent bands is 0.008 mass% or less. |
