Aluminum parts usually need to be oxidized before being sold on the market, so what properties does aluminum oxidation bring to aluminum parts? What are the effects of aluminum surface oxidation treatment?

The Internet of Things refers to the real-time acquisition of any object or process that needs to be monitored, connected, and interactive through various devices and technologies such as various information sensors, radio frequency identification technology, global positioning system, infrared sensors, laser scanners, and other necessary information such as sound, light, heat, electricity, mechanics, chemistry, biology, and location through various possible network access.

The reasons for the appearance of white spots after aluminum oxidation can be attributed to the following main factors:

7 series aluminum refers to aluminum zinc magnesium alloy, with high strength and good corrosion resistance, widely used in aviation, aerospace, automotive, machinery manufacturing and other fields. Hard anodizing is a process that forms a thick and hard oxide...

Anodizing is a common surface treatment process, mainly used to improve the corrosion resistance and wear resistance of aluminum. By forming a dense oxide film on the surface of the aluminum, anodizing can effectively protect the aluminum from environmental er...

As we all know, industrial Aluminum Profiles belong to alloy extrusion materials, and it is easy to damage the material and surface defects of the profiles due to improper operation of one step in the production and processing process. 

The material composition of aluminum products before the aluminum surface treatment is oxidized, and the influence of purity on the quality of aluminum oxide film has long been understood by scientific and technological workers.  

Aluminum Plate is widely used in our lives, we can also see everywhere, aluminum plate in the application of household appliances can be said to be very wide, such as refrigerators, microwave ovens, audio equipment, washing machine cylinder, kitchen utensils, including water tanks and other places where aluminum plate is used.

Due to the particularity of its production process, the surface defects of aluminum profiles directly or indirectly caused by the polishing quality of the mold or due to the process conditions in the hot extrusion process are as follows: coarse grain, color separation, dark band, bright band, line, bone (concave bone, convex bone), poor finish.
