Anodizing converts the surface of aluminum into a film of aluminum oxide (Al₂O₃), known as alumina, through a controlled electrolytic reaction.
The result is a thicker, harder, and more durable layer. It is uniform, adherent, and highly resistant, providing corrosion protection, improving surface hardness, and delivering a homogeneous appearance across the entire surface.
An important property of anodizing is that the alumina layer is dielectric, which means it does not conduct electricity. While the aluminum beneath remains conductive, the anodized surface becomes an electrical insulator. For applications requiring electrical contact, specific areas must be masked prior to anodizing to keep conductive zones.
In this process, alumina forms directly on the part’s surface, becoming a protective barrier that extends service life and enhances performance under demanding conditions.
In addition to the natural aluminum color, the process allows for controlled coloring to meet both aesthetic and functional requirements.
The anodic layer protects effectively in humid and aggressive environments, preserving part integrity.
Increases surface hardness and extends service life against friction and abrasion.
Natural or colored finish with excellent lot-to-lot repeatability.
Alumina is dielectric and improves the adhesion of paints, adhesives, and sealants.
Thin film with excellent compatibility with adhesives and high corrosion resistance. Common in aerospace.
Versatile for decorative and industrial applications. Enables uniform coloring and consistent finishes.
Thicker, harder coating for parts exposed to heavy wear, friction, and severe loads.
This is a finish for aluminum components, with a gray/cobalt-gray appearance produced through the anodizing process without the use of dye or pigment. Final appearance is subject to technical review and may vary depending on aluminum alloy, part geometry, process conditions, and customer requirements.
In addition to a natural finish, PAIMEX offers color application on parts. These finishes can also be carried out through co-development with the customer to create a specific color or finish tailored to your needs. Availability depends on requested requirements as well as part shape and size.
PAIMEX serves the aerospace, automotive, electronics, medical, telecommunications, and commercial sectors, supported by robust quality systems and third-party audits.
The process is designed for aluminum alloys. Compatibility depends on the series and end use—our team can advise based on your part.
It depends on service environment, expected friction, and specification requirements. We’ll recommend the optimal range for your application.
Protection comes mainly from thickness and sealing. Color is selected for aesthetics and functional needs.
When we hear the term anodizing, the first thing that comes to mind is that it is a type of paint applied to aluminum. While this has some truth, the reality is that the process itself is a way to protect the material against corrosion caused by atmospheric agents, as well as wear and tear that the anodized parts or pieces will be subjected to.
Through the anodizing process, an artificial film of aluminum oxide of a certain thickness known as alumina is obtained. This has the main characteristic of providing greater protection than other coatings as a result of the chemical and electrolytic processes involved in the procedure.
Anodizing can achieve a natural color of aluminum or any other color.
