Decoration and Durability

Standard Anodizing (Type II) Process Conforms to MIL-A-8625

Anodizing is an electrochemical process for producing controlled aluminum oxide films on aluminum. Oxide forms naturally on untreated aluminum, but the anodizing process produces a coating which is uniform, much harder, and more dense than natural oxidation. Aluminium oxide also possesses excellent thermal and electrical insulating qualities.

The anodic film is formed by converting the surface of the part into aluminum oxide. Unlike paint, which can flake off if not applied properly, anodized aluminum finishes are actually formed from the original material and cannot flake off. The aluminum oxide finish is very hard and exceptionally wear resistant.  Anodizing is good for many consumer products and sporting goods due to its aesthetic and corrosion protection properties. Anodizing is the primary finish for aluminum aircraft parts including major components before assembly and painting. We also offer PTFE coating to further enhance your parts resistance to wear.

NOTE: A crucial issue for designers to understand is that aluminum from the substrate is consumed in building the anodized coating. A rule of thumb is 50-50 penetration vs. build: about one thousandth of an inch of aluminum is consumed in building a coating thickness of two thousandths. This is even more pronounced on inside threads of parts. We highly recommend that you consult with our sales or process team prior to anodizing your parts if there are critical tolerances.

Color Anodizing

Aluminum parts can be anodized clear, or for a more decorative appearance, they can be dyed during the anodizing process to produce luxurious finishes with a deep color that can only be imitated by paint. Read more

Benefits of Aluminum Anodizing:

• High Corrosion Resistance
• Decorative / Cosmetic Appearance
• Insulator / Nonconductive
• Stain Resistance
• Increased Durability / Scratch Resistance
