Corrosion resistance describes the ability of a material to withstand damage caused by chemical or electrochemical reactions with the environment.
For aluminum:
- Aluminum forms a natural oxide layer (Al2O3) that protects it from further oxidation.
- This protective layer can be reinforced by anodizing.
- Particularly high resistance in neutral and slightly alkaline environments.
Significance:
- Longer service life of components.
- Less maintenance and repair costs.
- Use in damp or chemically aggressive environments, e.g. in the construction industry or in the maritime sector.
