Anodized film characteristics
1. Anodic oxidation film insulation
Anodized film is generally non-conductive and has good insulating properties. At temperatures of 15~25°C, the resistance is 1013 Ω/㎡, and at 250°C, the hard anodized film has a resistance of 1017 Ω/㎡. The anodized film, as an insulating material, has unique features compared to other insulating materials, such as thin film, high-temperature resistance, and the ability to withstand the侵蚀 effects of steam and other corrosive gases. Its drawbacks include low elasticity, high moisture absorption, and low voltage resistance.

How to handle aluminum extrusions after oxidation?
What to note during the post-oxidation process of aluminum profiles: First, clamp the non-conforming workpieces onto the fixture used for aluminum anodizing, perform hard anodizing, then subject the aluminum to anodic treatment in sulfuric acid solution for 2-3 minutes. Once the film becomes soft and peels off, gently clean with alkali solution and then brighten with nitric acid before re-initiating the conductive anodizing process.

Several unique methods for anodizing
Metal exposed to the air can easily oxidize and corrode, shortening the lifespan of equipment. We can actually protect it using methods like Nantong anodizing, which involves applying a protective layer to solve the problem effectively. Therefore, anodizing can apply a protective film to steel, utilizing the metal surface to form a tightly bonded anodic protective layer upon oxidation by oxygen and oxidizing agents in the air, isolating oxygen externally. In an anodizing plant, oxidation typically involves methods such as anodizing, acidic/alkaline oxidation, thermal oxidation, and chemical oxidation, among others.
