AN ALUMINIUM ALLOY ROLLED PRODUCT WITH INTENSE IRIDISCENT COLORS

摘要

The present invention is directed to an anodized decorative rolled product made of an aluminum alloy consisting of, in weight %,; Mg : 0 –1.5; Mn : 0 –1.5; With Mg + Mn : 0.5 –3 and wherein either Mn : 0.8 –1.5 or Mg : 0.5 –1.1 and Mn ≤ 0.2; Si : ≤ 0.6; Fe : ≤ 0.8; Ti : ≤ 0.1; Cu : ≤ 0.3; Cr : ≤ 0.1; Zn : ≤ 0.25; Zr : ≤ 0.1; other elements ≤ 0.05 each and ≤ 0.15 in total, remainder aluminium,; wherein the rolled product has a porous anodic oxide film which is colored electrochemically or chemically and wherein the color of the decorative sheet is different if viewed at an incidence angle 0° and at an incidence angle of 45°. The product of the invention is particularly useful for decorative applications such as cosmetic packaging, automotive trims (exterior and interior), interior design, sound system and consumer electronics.
