Golden/Silver Round Anodized Aluminium Bottle, For Essential oils, Capacity: 1 L

Aluminum anodized bottles are made of aluminum and have a protective layer of aluminum oxide on the surface. This layer is created by an electrochemical process called anodizing, which increases the thickness of the oxide layer on the surface of the bottle. The oxide layer is extremely hard and provides the bottle with high wear resistance and corrosion protection. Anodizing also improves the aesthetics of the bottle. The thickness of the oxide layer depends on the purpose of anodizing. For decorative purposes, a thin layer is enough, while a thicker layer protects the surface besides improving the appearance. The anodic layer is insulative and does not increase the strength of the aluminum object 1. I hope this helps! Let me know if you have any other questions.
