Anodizing is an electrochemical reaction process. Immersing the aluminium profile into acidic electrolyte solutions, here the aluminium profile is an anode, the cathode is installed inside the anodizing tank.
Under specific conditions and electric current, forming an oxide layer on the surface of the aluminium profile. The film thickness can reach 10-25 micrometres(Zhonglian Aluminium Factory).
(Noted: The white scratch in the figure above is the thread tying mark during oxidation, which is a normal phenomenon and can be sawed later.)
Oxidation treatment is the most common surface treatment method for aluminium profiles, which is widely used and highly regarded. You can hardly find mechanical lines on the surface(better than other factories) with beautiful fine sand blasting processing. The surface can hardly be scratched with an anodizing thickness between 10 and 13 μm.. Small scratch marks can be easily removed. However, other profile products with the same color in the market would easily be bruised because of a smaller thickness, and it's also difficult to remove the scratch marks on their surfaces.
As a comprehensive aluminium profile factory with 30 years of experience, Guangdong Zhonglian Aluminum Co., Ltd. uses national standard aluminium ingots as raw materials, ensuring that all extruded aluminium profiles have stable and high-quality characteristics.
Regarding the mentioned The Matt Anodized aluminium profile in this article, its surface has a certain roughness and delicate sandblasted texture. At the same time, it has excellent wear resistance and high hardness, which makes it difficult to be scratched or damage.
