Small anodized aluminum extrusions is a common manufacturing process mainly used to improve the corrosion resistance and aesthetics of aluminum alloy products. Aluminum profiles are first extruded, then subjected to deep CNC machining and finally surface treatment. During the process, the aluminum profiles are machined into specified sizes and shapes, and then an oxidized film is formed on the surface to give them better corrosion resistance and decorative properties.
