Anodic Oxidation

Are you still worried about aluminum alloy oxidation? BOZNA has a professional design team and service team, which can provide the best service to help you solve your problems.

Anodizing and passivation

Anodizing refers to the process of oxidizing aluminum and its alloy in the electrolyte environment by the action of external current, and forming an oxide film on the metal surface. The oxide film makes the product protective, decorative, insulating and wear resistant. Membrane pores have strong adsorption capacity, can form red, pink, blue, green, black and other appearance effects. Passivation refers to the process of forming an oxide film on the surface of a metal product by chemical soaking. The oxide film can protect the material and improve the resistance to atmospheric corrosion. And because the oxide film is thinner, can be the product to maintain its material's primary color.

How to do Aluminum alloy oxidation?

  • Degreasing and degreasing cleaning: remove oil stains, dirt and other impurities attached to the aluminum alloy surface. Using aluminum cleaning agent, environmentally friendly formula, does not corrode aluminum parts, and the surface of aluminum parts does not change color after cleaning. It can be soaked, sprayed and ultrasonically cleaned. The speed of degreasing and decontamination is fast, generally only need to soak for 1-3 minutes to clean thoroughly.
  • Chemical solution to remove oxide layer: Aluminum is easy to oxidize, surface oxidation spots will affect the overall appearance, and affect the adhesion of paint, especially easy to form pits, because the process of aluminum chemical polishing to remove oxide layer is an essential process before passivation . The use of chemical aluminum polish can quickly improve the gloss of aluminum, achieve a mirror effect, and remove burrs. The operation is simple, just soak at room temperature.
  • Aluminum passivation: soak in the aluminum passivation solution, the passivation time is 1-5 minutes, the purpose of passivation treatment is to form a dense and uniform continuous film on the surface of the aluminum alloy, that is, the passivation protective film, which can effectively improve the surface of the aluminum plate. antioxidant and anti-corrosion properties.
  • Soak in pure water and dry the package: the estimated time is 3 minutes. This process is a necessary one. Because the chloride ions in tap water usually attach to the surface of the aluminum parts, it needs to be soaked in pure water to prevent the residual chloride ions and prevent the aluminum veneer from being corroded. After the whole process is processed, the packaging can be dried.

Advantages of Electroplating Production Lines


Extremely durable and corrosion resistant, anodizing is a protective oxide layer that forms on the surface of aluminum, meaning it won't flake, chip or flake like other surface coatings. This makes anodized aluminum extremely durable and long-lasting.

Aesthetics Angle

Anodizing can produce a range of colors and finishes that enhance the appearance of aluminum. This makes it a popular choice for architectural and decorative applications, such as building facades and interior design.

Environmentally Friendly

Anodizing is an environmentally friendly process that produces no harmful by-products. The use of non-toxic dyes and sealants also minimizes environmental impact.
