Abstract
Described herein are anodized continuous coils containing a thin anodized film layer and methods for making and using the same. The anodized continuous coils include an aluminum alloy continuous coil, wherein a surface of the aluminum alloy continuous coil comprises a thin anodized film layer. The anodized continuous coils maintain the anodized film layer during deforming processes.
Claims20
An anodized continuous coil, comprising:
- an aluminum alloy continuous coil, wherein a surface of the aluminum alloy continuous coil comprises a thin anodized film layer.
A method of making an anodized continuous coil, comprising:
- providing an aluminum alloy continuous coil, wherein the aluminum alloy continuous coil is processed in a metal processing line having a preselected line speed;
- preparing a surface of the aluminum alloy continuous coil;
- and
- anodizing the surface of the aluminum alloy continuous coil in an electrolyte to form a thin anodized film layer, wherein anodizing parameters are tailored to the line speed of the metal processing line.
