Aluminum black anodizing is a process that builds a hard, colored surface on aluminum. The metal is placed in an acid bath and connected to electricity. This creates an oxide layer on the surface. Black dye is added to this layer while it’s still open. The part is then sealed to trap the color and protect it.

Metal surface finishing alters metal surfaces through mechanical, chemical, or electrochemical processes. The process involves adding, removing, or reshaping metal surfaces to achieve specific characteristics. Common techniques include grinding, polishing, coating, and plating to improve functional properties and visual appeal.

When I speak with customers from around the world, the topic of the importance of surface finish for metal fabrication is a constant. As a
