6063 aluminum tube can be used in many places, in addition to the construction, in fact, there are also applications in daily necessities, such as rod box, mainly used as a handle, but have you found that 6063 aluminum tube handle will turn yellow after long-term use, that is why?Next 6063 aluminum tube manufacturers to give you a solution.

1. During the processing, the handle of 6063 aluminum tube did not fully contact with the conductive rod, which increased the resistance and reduced the time for the formation of the oxide film, resulting in the pulverization of the oxide film. As a result, the surface of 6063 aluminum tube turned yellow.

Ii. The 6063 aluminum tube is not cleaned before electrophoresis, and incomplete cleaning will cause the reaction between the acid in the oxidation film hole and the electrophoretic paint, resulting in the yellowing of the surface of the 6063 aluminum tube.

Iii. Nitric acid will be added to remove ash during handle processing of 6063 aluminum tube. Some nitric acid may be brought into the tank after cleaning the 6063 aluminum tube, affecting the oxidation of the surface of 6063 aluminum tube, thus resulting in the blackening of the surface of 6063 aluminum tube.We can add the neutralizer and just mix the PH.

The reason why 6063 aluminum tube handle will turn yellow after long-term use is solved here. If you need 6063 aluminum tube, you can contact us.
