Title: ALUMINUM LAMINATE AND METHOD FOR PRODUCING SAME
Abstract:
An aluminum laminate (10) comprises an aluminum substrate (1) having a first surface (1A); and an anodic oxide film (2) that is formed in contact with the first surface (1A) and has a second surface (2A), which is in a position that is separated from the first surface (1A) in a direction that intersects the first surface (1A). A surface layer that includes the first surface (1A) of the aluminum substrate (1) includes aluminum having a purity of 99.9 mass% or more, and 0.001 to 0.052 mass% of iron. The surface roughness Ra of the second surface (2A) of the anodic oxide film (2) is 20 nm or less. The mean width of profile elements RSm of the second surface (2A) of the anodic oxide film (2) is less than 30 µm. The thickness of the anodic oxide film (2) in a direction that intersects the anodic oxide film is 9 to 26 µm.
