Anodized

Anodized refers to a process to increase thickness and durability of the natural oxide layer on the surface of metal parts.

Part of speech: adjective
Definition: Anodization is an electrochemical technique used particularly on aluminum to enhance the metal's durability, corrosion resistance, and appearance. By passing an electrical current through an electrolytic solution, with the aluminum object serving as the anode, a thicker oxide layer forms on the surface than naturally occurs. This protective layer not only fortifies the metal against wear and corrosion but also can be dyed a variety of colors for aesthetic purposes. As a result, anodized aluminum is widely used in the jewelry industry for pieces that demand both the lightweight nature of aluminum and an extended lifespan, encompassing a wide array of colors to suit diverse design needs.
