  • Patent number: 9970080
    Abstract: Micro additions of certain elements such as zirconium or titanium are added to high strength aluminum alloys to counter discoloring effects of other micro-alloying elements when the high strength alloys are anodized. The other micro-alloying elements are added to increase the adhesion of an anodic film to the aluminum alloy substrate. However, these micro-alloying elements can also cause slight discoloration, such as a yellowing, of the anodic film. Such micro-alloying elements that can cause discoloration can include copper, manganese, iron and silver. The micro additions of additional elements, such as one or more of zirconium, tantalum, molybdenum, hafnium, tungsten, vanadium, niobium and tantalum, can dilute the discoloration of the micro-alloying elements. The resulting anodic films are substantially colorless.
