Aluminum Sheet For Anodizing

August 29, 2022

The grades of aluminum sheet for anodizing are 5005, 5052, 6061 and 6063 aluminum sheet alloy with 0.1 -3mm thickness. The anodised aluminum sheet after anodizing have good appearance and high quality. In recent years, anodized aluminum sheet has also begun to shine in construction projects. As designers pursue large surface, high appearance, and smooth effect, anodized aluminum composite panels have become popular. With a flat, clean, luxurious image, excellent product performance, hard as sapphire and smooth as chrome. Anodized aluminum has a matte, low-reflection color that is favored by luxury brand projects. Whether it is a residence, a hotel, or a fashion car dealership, or even an art gallery or gallery, it is perfect.


Anodized aluminum is an extremely hard substance with the same molecular structure as ruby and sapphire. The aluminum sheet for anodizing surface naturally forms a layer of aluminum oxide, which is impermeable to water and only 4 mm thick. Anodizing is an electrolytic process that greatly increases the toughness of the aluminum oxide layer. The anodized layer can be dyed to create a range of color effects while still showing the luster of the underlying aluminum. Anodized aluminum sheet not only provide a unique smooth finish, they are also as tough as nails.

Today, I will take you to understand that aluminum sheet for anodizing is widely used in building facades, curtain walls, interior wall tops, etc., with a strong sense of visual impact.

1, Summary of materials

Anodized aluminum sheet is to place the aluminum sheet in the corresponding electrolyte (such as sulfuric acid, chromic acid, oxalic acid, etc.) as an anode, and under specific conditions and the action of an applied current, electrolysis is performed to form a dense oxide film on the surface of the aluminum sheet. The colorless and porous nature of the oxide film is used to achieve the purpose of dyeing and protecting the aluminum substrate.


2, the process of anodizing

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