1. What is anodized aluminum sheets/coil

What is anodizing

Electrochemistry is used in anodizing, particularly in the anodizing of aluminum. A dense oxide film is created on the surface of the aluminum plate after the material is exposed to an electrolyte solution. The name of this procedure is surface anodizing.

The anodized aluminum plates' surface treatment method is distinct from conventional printing technology. It electrolyzes the conductive acidic electrolyte using electric current, oxidizing the aluminum metal's anode surface, and creating a thick and fine layer of aluminum oxide protection on the aluminum surface naturally. This oxide coating is not a separate layer and won't peel off.

An electrochemical oxidation process is used to treat the aluminum surface in anodized aluminum plates. A tough and corrosion-resistant oxide coating can be created on the aluminum surface using this treatment technique. This oxide film can strengthen the aluminum plate's hardness and wear resistance as well as its surface decoration and anti-corrosion qualities. It is widely employed in several industries, including building, transportation, and aircraft.

Anodizing process

Anodizing can improve the corrosion resistance, surface hardness, and wear resistance of aluminum alloy products, and it has a good decorative effect after coloring treatment.

The anodizing process mainly consists of degreasing → etching → neutralization → anodizing → coloring → sealing.

Why is aluminum anodized?

After prolonged use, the aluminum plate will rust in the air. Although the surface's natural oxide layer has some passivation properties, prolonged overexposure will nevertheless cause the film layer to peel off, corrode, and change the color of the aluminum plate. The metal plate needs to be anodized in order to overcome this flaw and get the desired result. A thick oxide film develops after anodizing on the aluminum plate's surface. The anodized film's colorless and porous properties are used to dye and safeguard the aluminum matrix.

6. Applications and characteristics of anodized aluminum sheets/coil

1. High hardness and good corrosion resistance In the anodizing experiment, the aluminum plate is used as the anode and submerged in the appropriate electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.). Electrolysis is carried out under controlled circumstances using an applied current. A thin layer of aluminum oxide is created on the anode's aluminum plate after it has undergone oxidation. The hard anodized film can be as thick as 60 to 200 m, and its thickness ranges from 5 to 20 m. The product has a high degree of hardness, excellent insulation, great resistance to corrosion, and a high capacity for adsorption.

2. Anti-fouling and fire-proof, high safety The product's surface doesn't corrode, doesn't leave fingerprints or stains, and is simple to clean. The surface is unpainted and devoid of all chemicals. It doesn't burn at 600 degrees or release harmful fumes. It conforms with regulations for environmental and fire safety.

3. Good weather resistance and suitable for processing When utilized indoors for a prolonged period of time, the anodized aluminum plate with a standard thickness oxide film (3 m) will not corrode, oxidize, or rust. The thicker oxide film (10 m) on the anodized aluminum plate allows it to be used outside without fading even after prolonged exposure to sunshine. High-speed continuous stamping of the items makes it possible to turn them directly into finished goods. Complex surface treatment is not required, which significantly shortens the product production cycle and lowers production costs.

A popular option for materials to decorate buildings is anodized aluminum panels. The most crucial aspect is that anodized aluminum panels, thanks to their lighter weight and simple installation, may not only assure brilliant and lovely decorative effects but also produce a safer ornamental style.
