We will introduce the technical data on the physical properties of anodized oxide films.
Aluminum has good thermal and electrical conductivity, and it forms a natural oxide film in the air that protects the interior. However, the artificially generated insulating anodized film has a strong adhesion to the material and forms a coating with excellent toughness, corrosion resistance, and wear resistance.
