The Manufacturing Process of Anodized Aluminium Sheet

The anodizing method is a process in which aluminum or aluminum alloy products are used as anodes and placed in an electrolyte solution to form an aluminum oxide film on the surface. The thickness of the anodized film of aluminum and its alloys can reach tens to hundreds of microns.

The anodized aluminum sheet not only has good mechanical properties and corrosion resistance, wear resistance, weather resistance, but also has strong adsorption performance. Then, it can be electrolytically colored. The anodizing process is: Pretreatment -anodizing-electrolytic coloring (bronze or titanium)-sealing-unloading.

Anodised aluminum plate is widely used in various fields, such as mobile phones, computers, aircraft, auto parts, precision instruments, radio equipment, daily necessities and architectural decoration. Different applications have different requirements for the anodizing process.

The color film obtained by electrolytic coloring process of aluminum plate has good wear resistance, light resistance, heat resistance and chemical resistance, and is widely used in modern buildings. Richer colors are generated such as silver white, bronze, dark red,etc.

The anodized aluminum sheet is of good corrosion resistance, stain resistance, fingerprint resistance, and good thermal conductivity, so it is also widely used for electronic products to improve their texture and performance.

With the development of shipping industry in various countries and the need of efficiency, more and more high-speed passenger ships use aluminum alloy as the hull structure. The corrosiveness of seawater is very strong, therefore aluminum alloys often have to undergo corresponding surface treatment to improve its adaptability to the surroundings.
