Aluminum housings are various housings made of aluminum alloys. Aluminum shell is a commonly used material in social production and has a wide range of applications in various industries. The aluminum casing needs to undergo an oxidation process during the production process. Do you know what the oxidation treatment of aluminum casing is? The following will introduce to you: The oxidation treatment of the aluminum shell of Aluminum Machining can achieve strong anti-oxidation ability, which greatly prolongs the aging and discoloration of aluminum profiles. The oxidation treatment of aluminum casing involves many disciplines such as metallology, chemistry, and informatics. Aluminum and its alloys are passive in the atmospheric environment. The traditional ferrous metal surface treatment process has poor surface adhesion, and it is difficult to achieve satisfactory maintenance results. 

       The oxidation of the aluminum shell is easy to form a chemical conversion film with excellent performance, which plays a good protective role. Therefore, in the oxidation treatment technology of aluminum shell, the application of chemical conversion coating technology is more and more extensive. In CNC Machining, the metal surface is inevitably oxidized during heat treatment, machining, transportation and storage, forming an oxide layer with an uneven thickness.

        At the same time, it is also contaminated with various oils and adsorbs some other impurities. Oil stains and some adsorbates, as well as thin oxide layers can be cleaned with solvent, chemical treatment and mechanical treatment in sequence, or directly with chemical treatment. If the oxide layer is thick and the oxidized metal surface is serious, it cannot be cleaned directly, and chemical treatment with solvent is not allowed. First need for mechanical treatment
