Anodized aluminum

Anodizing is a process used to increase the thickness of the natural oxide layer on the surface of metal parts. It increases corrosion and wear resistance, and during the process the anodized aluminum surface can be dyed into many different colors,such as gold anodized aluminum sheet,black anodized aluminum sheet,white anodized aluminum sheet ect.

Basic principle: aluminum cathode oxidation is essentially the electrolysis of water. When water is electrolyzed, O2 – ions react with anodic aluminum to form alumina (Al2O3). Generally, sulfuric acid, chromic acid, phosphoric acid and oxalic acid are selected as the electrolyte to form a hard porous oxide film in sulfuric acid at about 0C. Different materials have great influence on the oxide film. For 6000 series Al Mg Si (6063.6061.6065), it can form not only protective oxide film, but also dyeing oxide film and bright oxide film. However, for cast aluminum alloy, it can form protective oxide film, but dyeing oxide film can only form thick color.

Anodized Aluminum is stronger and more durable than mill finish aluminum. The process of anodizing allows for the steel to embody these characteristics. Anodizing involves an aluminum coil or sheet being placed into a chemical acid bath. An electrical current is passed through the acid, causing the surface to oxidize. The oxidation forms a strong coating on the surface of the aluminum.

Anodize aluminum is commonly found in applications where the material may be exposed to the elements. It is also found in kitchen equipment like pots and pans because the material distributes heat evenly.

Why does aluminum sheet need to be anodized finish?

Anodized treatment can make the gloss of the metal surface remain unchanged for a long time, improve the corrosion resistance and mechanical strength, and obtain a decorative appearance after dyeing. Anodized finish aluminum sheet is used in many places. Here are a few examples. Prevent product corrosion: The film layer obtained by the oxidation of the positive electrode has been properly sealed and has g ...

Teach you how to judge mirror anodized aluminum sheet

Method 1: mirror anodized aluminum sheet, after ripping off the protective film, touching the mirror with your fingers, the sweat stains on your fingers will stay on top of the mirror, but after scrubbing with a dry cloth or paper towel, fingerprints will be wiped clean and will not leave any trace. Not after the oxidation of the mirror aluminum plate is not the same, leaving the fingerprints will be more and ...

Not all aluminum sheet is suitable for anodizing processing

In high-rise buildings, we can sometimes see the color white curtain wall aluminum plate, obviously different from the surrounding color, very affect the appearance. It can be seen that not all aluminum sheet is suitable for anodizing processing, hot-rolled aluminum plates are more suitable for anodizing processing base material. Some enterprises in the use of our aluminum sheet products after processing m ...
