Anodized aluminium profile is surface-treated aluminum profiles. Anodizing surface treatment can enhance the surface hardness, corrosion resistance and wear resistance of aluminum profiles, while also improving their appearance.

What are anodized aluminum profiles?

Anodized aluminium profiles refer to the use of chemical methods to form an oxide film on aluminum materials. But unlike general oxide films, anodized aluminum can be dyed with electrolytic coloring. Anodized aluminum profiles have better wear resistance, heat resistance and corrosion resistance.

Using range of anodized aluminium extrusions

Anodized aluminum profiles have a wide range of applications. The following are common application industries:

  1. Construction and architectural decoration: Anodized aluminum profiles are used in construction to manufacture windows, doors, curtain walls, balcony railings, stair handrails, roofs, facade panels and other components.
  2. Electronics and electrical industry: Anodized aluminum profiles are used to manufacture electronic equipment casings, radiators, connectors, conductive materials, electronic radiators, etc.
  3. Automobile industry: Anodized aluminum profiles are used in automobile manufacturing to manufacture body parts, doors, roofs, window frames, engine parts, etc. Helps reduce the weight of the car itself.
  4. Industrial equipment: It is often used in manufacturing machinery and equipment, conveyor systems, assembly lines, machine parts, etc. to provide strong and durable materials.
  5. Aerospace field: In aircraft and spacecraft manufacturing, anodized aluminum profiles are used to make components and casings.

What are the colors of anodizing aluminium profiles?

The color of anodized aluminum profiles can be varied through different dyes and treatments. Anodized aluminum profiles come in many colors.
Common anodized aluminum profile colors: silver white, bronze, champagne, black, gray, white, etc. We will customize the required colors according to your specific needs.

Aluminium profile anodizing process

  1. Pretreatment: First, the aluminum profiles need to be cleaned to remove impurities, grease and dirt on the surface.
  2. Anodizing: The aluminum profile is immersed in an acidic solution containing sulfuric acid or oxalic acid, and then an electric current is applied to the aluminum to form an oxide film. This oxide film is a hard aluminum oxide layer formed on the surface of aluminum, enhancing its hardness and corrosion resistance.
  3. Dyeing (optional): Dyeing is an optional step in the anodizing process, which can change the color of the aluminum profile. During the dyeing process, aluminum profiles are soaked in dye so that the color is absorbed into the pores of the oxide layer.
  4. Sealing treatment: Finally, dyed or undyed aluminum profiles are usually sealed to lock in the oxide layer and further improve their corrosion resistance.

Why should aluminum profiles be anodized?

  1. Decorative. After the aluminum profile is anodized, a protective film will be formed on the surface, and this protective film is highly translucent. If dyes of other colors are added, a colored oxide film will be formed.
  2. Non-conductive. We know that aluminum profiles themselves are conductive, and many electrified frames cannot be used. However, after the aluminum profile is anodized, it no longer conducts electricity. Therefore, many live equipment can be made of aluminum profiles.
  3. Anti-corrosive. Since the film layer obtained by anodization itself has sufficient stability in the atmosphere, the oxide film on the aluminum surface can be used as a protective layer. The oxide film obtained by anodizing aluminum in a chromic acid solution is dense and has good corrosion resistance.
