Anodizing process is an electrochemical process that includes dipping aluminum in a chemical bath that forms a hard layer of aluminum rust on the surface.
This anodizing process makes it resistant to chemical reactions while cooking. The cookware becomes more durable after applying current between the electrodes during a chemical bath.
This process also makes the aluminum stronger so it lasts longer in high-pressure situations. Also, the anodized layer of protection resists corrosion and minimizes the impact of forceful blows and scratches.
