Anodized and brushed aluminum enclosures primarily differ in surface finish. Anodizing forms a stable oxide layer on the aluminum surface, offering diverse color and finish options. Brushed aluminum enclosures use mechanical processing to create directional grain, delivering a pronounced metallic texture.

When choosing between them, consider aesthetic requirements, operating environment, touch frequency, cleaning methods, color, grain direction, and downstream processing. Parts can also be mechanically brushed first, followed by anodizing or other finishes per project requirements. The exact process combination depends on materials and engineering drawings.
