6. Conclusion

Anodizing aluminum and its alloys offers a wide range of possibilities in terms of the properties required for use. It often involves a compromise between the metal's intrinsic characteristics, such as its mechanical properties, and its suitability for anodic oxidation. It is advisable to take this parameter into account right from the design stage, particularly when choosing the alloy.

Generally speaking, recent years have seen the development of processes that are more respectful of the environment, with a parallel strengthening of legislation in this respect. It is to be expected that future developments will follow this trend, although this does not rule out the possibility of improving or obtaining new properties for anodic layers.
