- Coating Thickness versus Dimensional Growth
During anodization, the surface of the aluminum is converted into aluminum oxide with half the oxide film grows outwards and half penetrating into the base aluminum. A 50 micron anodic film will result in a dimensional growth of 25 microns. On occasion, there is confusion when a coating thickness is specified without realizing the dimensional increase on the surface of a precision part is only half the coating specified. Care must be taken in the terminology used when specifying the buildup expected.
- Anodizing Characteristics of Different Alloys
Different alloys and tempers will exhibit different properties when anodized. The following link will give a description of the anodizing characteristics expected from different aluminum alloys.
