Anodized Aluminum Extrusions

Anodizing - Anodizing successfully combines science with nature to create one of the world's best metal finishes. It is an electrochemical process that thickens and toughens the naturally occurring protective oxide. The resulting finish depending on the process, is the second hardest substance known to man, second only to the diamond. The anodic coating is part of the metal, but has a porous structure which allows secondary infusions, (i.e. organic and inorganic coloring, lubricity aids, etc.) Tri State Aluminum has over 25 years experience in anodizing aluminum extrusions.

Electrolytic Coloring (The two-step method) - After anodizing, the metal is immersed in a bath containing an inorganic metal salt. Current is applied which deposits the metal salt in the base of the pores. The resulting color is dependent on the metal used and the processing conditions (the range of colors can be expanded by over dyeing the organic dyes). This process offers color versatility and the most technically advanced coloring quality.

Tri-State Aluminum specializes in anodized aluminum bars, rods, tubes and many other shapes. Contact us today for all of your extrusion needs!
