Materials Can Be Anodized: Useful, But Not Simple

Summary for materials can be anodized Discussion

What materials can be anodized? In this thread, Doug Horn asks which metals besides aluminum can be anodized. The reply explains that magnesium, stainless steel, titanium, and zinc can all form useful oxide skins when anodically oxidized under the right conditions. However, the answerer cautions that this does not mean they can simply be run in an aluminum anodizing tank or that they will produce the same results, such as dyeability or hardness. The key point is that anodizing depends on the material’s ability to form a useful oxide layer under the proper process conditions, so the question needs to be more specific for a better recommendation. The answer closes by inviting a more detailed question so the discussion can be narrowed to the exact material and outcome desired.
