Electrochemical bright treatment technology for aluminum tube can also be used to remove microcracks and embedded foreign impurities from the aluminum tube's surface, in addition to removing burr and other imperfections. In other words, the aluminum tube does not have any energy input into its surface, which allows it to be changed in terms of the surface tension and compressive stress of the tube. This surface becomes stress-free, which increases the product's fatigue resistance by a factor of two.
Using electrochemical bright treatment, it is possible to increase the corrosion resistance of aluminum tube products by 2-3 times. The aluminum tube has been electrochemically treated, resulting in the formation of a strengthened passivation film, which solves the chromium-poor nickel-poor layer on the surface, and the aluminum tube has formed an enriched chromium and nickel passivation layer.

It has been suggested by a leading aluminium tube supplier in China that after aluminum tube products have been electrochemically brightened, the cleanliness of the product will be enhanced. After electrochemical treatment, the surface of the workpiece is bright and the aluminum tube is smooth, making it difficult for dirt to adhere to the workpiece's surface after it has been polished. But after the electrochemical brightening treatment, scaling is much more difficult to accumulate, and the service life of the aluminum tube is significantly increased.
The degaussing process for aluminum tubes
1. An aluminum tube is wound around the outside of a steel tube, and the coil is energized with alternating current. As the current of the alternating current is reduced, the aluminum tube is reduced until it is completely depleted. Aluminum tube demagnetization results in the following: no change in the physical properties of the aluminum tube from CHAL Aluminium Corporation, but the aluminum tube will become magnetized once it is exposed to an external magnetic field again.
Through the use of heat treatment, it is possible to completely demagnetize an aluminum tube. The hardness and rigidity of the aluminum tube, on the other hand, will change after demagnetization. Should a future external magnetic field be encountered, the aluminum tube will be effectively demagnetized after the external magnetic field has been removed from the environment. It has no resemblance to anything else in the universe.
3. The heat treatment process for aluminum tubes is roughly as follows: the aluminum tube is heated to a specific temperature without the presence of oxygen, and then the aluminum tube is slowly cooled to room temperature over a 72-hour time period.
