We are a professional manufacturer of aluminum profile radiators. Some users may require us to perform oxidation treatment when they want to order our high-power profile radiators. So what is the use of oxidation treatment for aluminum shaped radiators, and why is this treatment necessary?

The phenomenon where the surface of a metal undergoes chemical or electrochemical interactions with the surrounding medium, resulting in damage to the metal, is commonly referred to as metal corrosion. The corrosion of metals causes huge losses to us every year. One of the methods to prevent metal corrosion is to form an oxide film protective layer on the metal surface. Many metals have natural oxide films, but most of them do not serve as protective layers.

Aluminum and aluminum alloys have the advantages of low density, high specific strength, good conductivity and thermal conductivity, easy forming, and no low-temperature brittleness. They are a light metal material with excellent comprehensive performance. At present, aluminum materials have been widely used in the aerospace industry, building materials, transportation vehicles, electronic products, and other fields. Aluminum has a strong chemical affinity for oxygen, and its surface is always covered by a transparent oxide film in the atmosphere. However, the natural aluminum oxide film is extremely thin, only 4x10-3-5x10-3 μ m. Moreover, the porosity is high, the mechanical strength is low, and the corrosion resistance and wear resistance cannot meet the needs of corrosion prevention.

Taking aluminum profile radiators as an example, electrochemical methods can be used to generate a dense and high-quality oxide film on the surface of aluminum (or aluminum alloys), with a thick film that can reach tens to hundreds of micrometers, effectively improving the corrosion resistance of aluminum. This electrochemical process that oxidizes the surface of aluminum is called anodic oxidation of aluminum. In addition, due to the uniform pores of the formed oxide film, organic dyes can also be used for dyeing. After sealing, the color is stable, making the application of aluminum materials more widespread.

However, oxidation treatment always comes with pollution, and the customers we cooperate with have good environmental awareness. Generally, the aluminum radiators they order will not undergo oxidation treatment unless it is necessary.

The above is an introduction by aluminum profile radiator manufacturers on why aluminum and aluminum profile radiators need to undergo oxidation, hoping to be helpful to everyone.
