The process of anodizing aluminum changes the surface chemistry of metals and other substrates resulting in superior mechanical properties. Anodizing can be done to a wide range of materials but aluminum is one of the most used metals in the process. The resulting product will have a durable surface finish that is protected from corrosion, an enhanced aesthetic quality, and can resist scratching. This clever surface treatment is practical at the same time beautiful thus you need to try it sometimes then you’ll do it again and again. To further convince you, here are 6 reasons why you should start anodizing.
