What is anodized aluminum?

Anodized aluminum is a process that involves electrolytically oxidizing aluminum to form a dense, uniform, and wear-resistant surface coating. This coating is widely used in metal processing due to its strong corrosion resistance, high hardness, and wear resistance, especially in the processing of aluminum materials, which can increase their aesthetics.

During the anodizing process, aluminum products are immersed in an acidic solution containing an electrolyte and subjected to direct current electrolysis. This forms a dense oxide layer on the surface of the aluminum, a process known as anodization.

Anodized aluminum is widely used in fields such as construction, automotive, aerospace, and furniture. It can be used to produce various products such as door and window frames, stair handrails, furniture accessories, etc.
