Anodizing: Process, Types, Benefits, Applications

Anodizing is the essential B2B electrochemical conversion process for aluminum. It transforms the surface into a hard, non-corrosive Al 2 ​ O 3 ​ ceramic layer, providing superior wear resistance (Type III), corrosion protection, and insulation. Best results require 6061/7075 alloys. Although the initial cost may be higher than coatings, its molecular adhesion and long-term durability deliver a higher overall ROI for critical applications in industries like aerospace and high-end electronics.
