Anodizing properties
Pure aluminum is resistant to corrosion, as it has a fine natural oxide layer on its surface that protects the metal from external factors. This layer is prone to damage due to its fragility, which is caused by both its thinness and inhomogeneity. The anodizing (anodizing) process allows the thickness of this oxide layer to be increased and controlled, resulting in a homogeneous and durable layer.
