Anodizing

Bright dip is a chemical polishing process that brightens and enables bold coloring of aluminum primarily for cosmetic applications. This is accomplished by leveling the microscopic roughness of the aluminum surface and increasing its specularity, leaving no deposits on the surface of the part and protecting the anodized product from metal corrosion, fading and scratching.

Sulfuric acid is the most widely used solution to produce anodize coatings. Type II is defined as having a modern thickness range between 0.00007” to 0.001”

Sulfuric anodizing is used on applications to improve its aesthetics, provide vibrant color coatings, and good wear and corrosion resistance. Sulfuric anodizing (Type II) uses conventional coating methods produced from a sulfuric acid bath, with the process taking between 20 to 60 minutes depending on the type of alloy used. Sulfuric anodizing increases the material’s wear resistance, corrosion resistance, ability to retain lubricants and PTFE coatings, and electrical and thermal insulation.

The Type III Hardcoat Anodize process produces superior hardness and denseness. When a part is hardcoated, it increases the micro finish 2-5 times, depending on the alloy.

Some industrial applications of Hardcoat Anodizing include highly intricate parts such as pistons, anti-lock brake assemblies, pump components, valves, sliding parts, insulation plates and transmission parts. Some retail applications for Hardcoat Anodizing and Sulfuric anodizing include cookware, bike rims, locks and levels.

Type III with PTFE is a hardcoat anodize with Teflon. This application is engineered to provide exceptional lubricity, wear resistance, and high levels of corrosion resistance. This type of anodize provides a good surface for aluminum molds, as the lubricity of the surface translates into superior release characteristics, and the coating remains stable at high temperatures. In addition, the synergy between the crystalline formation of the oxide film and the molecular structure of the PTFE yields a good wear characteristics.

Common industries that require Type III with PTFE are; Aerospace/Astrospace/Aviation, Firearms, Machinery, Electronics, Marine, Oil, Chemical Industry, and more.

Precision masking is used on parts that require multiple metal plating processes such as steel, aluminum, and copper. Precision masking is used for the application of different and often incompatible processes to the same part.

Some industrial applications of Hardcoat Anodizing include highly intricate parts such as pistons, anti-lock brake assemblies, pump components, valves, sliding parts, insulation plates and transmission parts. Some retail applications for Hardcoat Anodizing and Sulfuric anodizing include cookware, bike rims, locks and levels.
