CNC Turning Aluminum Anodize Product

We are SHENZHEN LITONG METAL POWER CO LTD.,which has 13 years OEM and ODM experiences. Welcome to visit us and business cooperation....

In addition to metals, other substances do the oxidation caused by the anode, also known as "anodizing."


In the actual process, for the anodized aluminum, more, can be used in everyday life, that the characteristics of this process, the aluminum surface to produce a hard protective layer, can be used for the production of kitchen utensils and other daily necessities. But the cast aluminum anodizing effect is not good, the surface is not bright, it can only be black. Aluminum profiles will be better.Iron CNC Milling Parts Supplier

Aluminum itself is a kind of material with strong corrosion resistance, but it will form oxidation of aluminum oxide on the surface of aluminum after encountering oxygen, so that if it takes a long time, it will gradually relieve his corrosion resistance and resistance to moisture. In addition, aluminum is very sensitive to acidic substances. When it encounters acidity, it will destroy the surface layer of aluminum. Then we need to be oxidized again to add a protective film on the surface to strengthen the corrosion resistance of the surface layer. After the material or product is anodized on the surface, its corrosion resistance, hardness, wear resistance, insulation, heat resistance, etc. are greatly improved. The most anodized metal material is aluminum. The anodization of the aluminum tube is generally performed in an acidic electrolyte with aluminum as the anode. CNC turning aluminum polish product Supplier In the electrolysis process, oxygen anions react with aluminum to produce an oxide film. The film is not sufficiently dense at the beginning of the formation. Although there is a certain resistance, negative oxygen ions in the electrolyte can still reach the aluminum surface to form an oxide film. As the film thickness increases, the resistance also increases, and the electrolytic current becomes smaller. At this time, the outer oxide film in contact with the electrolyte is chemically dissolved. When the rate of oxide formation on the aluminum surface gradually equalizes with the rate of chemical dissolution, this oxide film can reach its maximum thickness under this electrolytic parameter. The anodized film of aluminum has a porous outer layer, which easily adsorbs dyes and colored materials, thereby dyeing and improving its decorative properties. After the oxide film is further treated with hot water, high temperature water vapor or nickel salt, it can further improve its corrosion resistance and wear resistance. In addition to aluminum, industrially used surface anodized metals include magnesium alloys, copper and copper alloys, zinc and zinc alloys, steel, cadmium, niobium, zirconium, etc.Metal aluminum brush part Supplier
