The difference of surface color of different types of aluminum profiles after conductive chemical conversion treatment is more obvious than that of oxide films obtained due to different process formulas. High aluminum purity and slow film-forming speed; If the purity of aluminum is low, the opposite is true. Therefore, it is necessary to master different parameters according to different aluminum profiles during oxidation. In order to achieve this, different types of aluminum sections are not allowed to be bound in the same string, so as not to control their appropriate oxidation time.

The advantages and disadvantages of aluminum profile composition can be distinguished during alkali etching. If there are too many gray black films or red films on the surface of the workpiece after alkali etching, it must be aluminum with high silicon or copper content. The chemical conversion time of this aluminum should be shortened, otherwise the obtained film will not meet the conductivity requirements.
