๐งชAnodizing
Anodizing is the process of electro-chemically controlling and enhancing the oxidation of aluminium substrate. The process converts the metal surface into a tremendously durable coating; because of the coating, the surface becomes extremely hard. Anodizing combines science and nature through a highly controlled oxidation, an advanced form of a natural phenomenon. Based on the functionality of the part, different types of anodizing are selected.
