What is The Oxidation Treatment For The Aluminum Shells?

Aluminum shells are various types of shells made of aluminum alloy. Aluminum shell is a commonly used material in social production and has a wide range of applications in various industries. Aluminum shells need to undergo oxidation treatment during the production process. Do you know what oxidation treatment is for aluminum shells?

The oxidation treatment of aluminum shell can achieve strong antioxidant capacity, greatly prolonging the aging and discoloration of aluminum profiles. The oxidation treatment of aluminum shells involves multiple disciplines such as metallurgy, chemistry, and informatics. Aluminum and its alloys are passive in atmospheric environments, and traditional black metal surface treatment processes have poor adhesion to their surfaces, making it difficult to achieve satisfactory maintenance results.

Aluminum shell oxidation easily forms a high-performance chemical conversion film, which plays a good protective role. Therefore, in the oxidation treatment technology of aluminum shells, the application of chemical conversion coating technology is becoming increasingly widespread. During heat treatment, machining, transportation, and storage, the metal surface is inevitably oxidized, forming an uneven layer of oxide.
