Aluminum coil manufacturerExplain the difference between anodizing and conductive oxidation of aluminum alloys

1) Anodic oxidation is carried out under high voltage, and it is an electrochemical reaction process. Conductive oxidation (also known as chemical oxidation) does not require electrification, but only needs to be soaked in medicinal solution. It is a pure chemical reaction.

2) Anodizing takes a long time, with Wangwang taking tens of minutes, while conductive oxidation only takes a few tens of seconds.

3) The film generated by anodic oxidation ranges from a few micrometers to several tens of micrometers and is hard and wear-resistant, while the film generated by conductive oxidation is only 0.01-0.15 micrometers. The wear resistance is not very good, but it can conduct electricity and resist atmospheric corrosion, which is its advantage.

4) The oxide film is originally non-conductive, but because the film generated by conductive oxidation is really thin, it is conductive.
