Anodizing aluminum forms a hard, uniform oxide layer that improves corrosion resistance, increases hardness and surface wear resistance.
The thickness of the oxide layer is usually controlled by factors such as current density, electrolyte composition, and operation time during the anodizing process. These parameters affect the growth rate of the oxide layer.
Anodizing is widely used in aerospace, automotive, construction, and electronics industries to provide protection and modification of metal surfaces.
The main purposes of anodizing include increasing corrosion resistance and hardness, improving the surface appearance, and providing specific color options in some cases.
Dyeing is an optional step, typically used to change the color of the oxide layer to meet various aesthetic needs. It offers a wide range of color for anodized parts.
