★ Conversion film thickness

        The chemical conversion film on the surface of aluminum alloy is about 0.5~4um thin, 5056 aluminum conversion film is a kind of gel, it is difficult to measure accurately immediately, usually only weighing the net weight of the workpiece before and after chemical oxidation, or surface color and salt spray test to distinguish the corrosion resistance of oxidation film.

        Anti-rust effect after scratch

        Anodic oxidation oxidation is realized in the case of high voltage line, 4043 aluminum profile is a kind of electrochemical reflection process; Conductive oxidation (also known as chemical oxidation) is not plugged in

        The chemical transformation film on the surface of aluminum alloy is a kind of gel. The colloid solution can move after the transformation film is scratched, and the suspected glue around the scar will move to the scratch surface, combined together, again, prevent the aluminum alloy from being etched, and still have corrosion resistance.

        Taken the tone

        The color of aluminum alloy chemical conversion film is dark gray, milky white, light green, orange yellow, rainbow color. The final color of the conversion film depends on the drug solution of the conversion film selected and the actual processing conditions.
