Applied Anodize Inc.
Why anodize your aluminum?
- Selective Electrical Conductivity
- The Electrical Conductivity is achieved in many ways but the foundation is the same for all methods. Once a few details are known, we can suggest the best method for satisfying your needs.
- If the Electrical Conductivity needed is going to be static, then a clear chemical conversion film, a gold chemical conversion film, or a deposited metallic film such as gold will satisfy the demands of the application.
- For more detailed information please contact us, so that we can suggest the optimum combination of options.
- If the Electrical Conductivity needed is going to be dynamic, then a more robust system will be needed. Typically we start with a clear chemical conversion, precision mask the necessary area and then place a metallic coating on top of the base material to protect against corrosion while at the same time be hard enough to withstand the wear associated with a dynamic connection.

- Low elemental contaminant levels
- When aluminum is anodized, there are no added metallic elements.
- The anodic coating is literally grown from the base material. As the anodic coating is formed, it penetrates and grows on the base metal by converting aluminum to aluminum oxide.
- The ratio of growth/penetration for anodic coatings is typically 50/50.
- Our experience has shown very low contaminant ranges
- Calcium - 6,000 x 10 10 atoms / cm2.
- Nickel - 500 x 10 10 atoms / cm2.
- Potassium - 5,000 x 10 10 atoms / cm2.
- Sodium - 5,000 x 10 10 atoms / cm2.
- Note – 6061 Aluminum with a Clear (no dye) Class 1 Type III 2 mil coating with a Ultra High Purity Water seal is the coating used for testing.
