Typically, the thickness ranges from 3 to 12 μm. With hard anodizing, thicknesses of over 50 μm are possible depending on the material.
The process of quickly generating a very thin film of aluminum oxide (Al2O3) by chemically reacting with oxygen in the air is commonly referred to as "anodizing." Formally, it is called aluminum anodic oxidation film, and typically has a thickness of 3 to 12 μm, while hard anodizing can achieve thicknesses of over 50 μm depending on the material. Currently, there is ongoing development of media that can store electronic data in the fine pores (diameter 0.1 μm) that make up the anodized film, drawing attention for uses that differ from the original purpose of the film.
