Anodizing is most often we used surface treatment way on aluminum cnc produts.
Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish.
Many metals are structurally weakened by the oxidation process, but Aluminum is ideally suited to anodizing,
Aluminum parts can actually be made stronger and more durable through anodizing.
An electric current passes through the acid, causing the surface of the aluminum to oxidize (essentially rust).
The oxidized aluminum forms a strong coating as it replaces the original aluminum on the surface.
The result is an extremely hard substance called anodized aluminum.
Anodized aluminum can be nearly as hard as diamond under the right anodizing process.
Many modern buildings use anodized aluminum in places where the metal framework is exposed to the elements.
Anodized aluminum is also a popular material for making high-end cookware such as frying pans and pots.
Heat is distributed evenly across anodized aluminum, and the process of anodizing provides a naturally protective finish.
