Introduction to common methods of aluminum oxidation processing

In practical applications, oxidation treatment is often required for aluminum and aluminum alloy profiles. So, what are the methods for aluminum oxidation processing, do you know? This article will list four common aluminum oxidation processing methods to explain, I hope to help everyone learn and understand.

One of aluminum oxidation processing methods: natural oxidation

Although the cost of this processing method is low, there are many problems. Not only will it take a long time, but the protective film formed on the surface of the material is thin and the protective ability is weak. Generally, the thickness is about 0.5 to 4 Between micrometers. In addition, such an aluminum oxidation processing method will be porous, and the texture of the material is soft, and the improvement of the corrosion resistance and wear resistance of the material is not obvious. However, it also has advantages, that is, strong adsorption.

Aluminum oxidation processing method two: electrochemical oxidation

Compared with the previous processing method, this processing method has a certain improvement in the thickness of the formed oxide film. In general, the achievable thickness is 5-20 microns, and the hardness has also increased, and it also has a certain Insulation and heat resistance. Not only that, but in addition, the corrosion resistance formed by electrochemical oxidation is also good.

Aluminum oxidation processing method three: chemical oxidation

This method is more commonly used now because it is more convenient in operation and has higher production efficiency. This also shows that the use of chemical oxidation method for aluminum oxidation processing is a processing method, which has a wide applicability, and the outstanding point is that it can be used to process products of different sizes and different specifications and shapes.

Aluminum oxidation processing method four: anodizing

This method is currently popular, and experiments have shown that after the treatment of this aluminum oxidation processing method, the obtained aluminum material has a significant improvement in performance. Moreover, for different products, different concentrations of electrolyte can be used, so the conditions of oxidation processing can be flexibly controlled
