Process features:
Renchang aluminum alkaline weak corrosive removes the oxide film and oil film on the surface of the workpiece to form a uniform sand surface, which is conducive to the formation of good bonding force in subsequent processes.
The corrosion rate is uniform and will not cause local erosion. It is suitable for weak corrosion of aluminum substrates.
