Aluminum Surfaces: A Systematic Approach
Rixal®
RIXAL® is Rieger Metallveredlung’s premium brand for high-performance aluminum surfaces. Under this brand, we bring together our in-depth knowledge of materials, our experience in aluminum finishing, and specially developed coating systems for technical applications.
After all, aluminum is not a standard material. And the right surface finish doesn’t happen by chance—it results from an understanding of the alloy, the application, the geometry, and the stresses involved.
RIXAL® stands for Rieger × Aluminum.
What is RIXAL®?
More than just a procedure
Aluminum is lightweight, versatile, and indispensable in many industrial sectors. At the same time, this material places high demands on surface finishing. Aluminum can behave differently depending on the alloy, material condition, and component geometry. Added to this is the natural oxide layer that forms immediately on the surface and can affect subsequent coating processes. For this reason, it is often not sufficient to simply select a standard process.
To ensure reliable results, you need a thorough understanding of:
- the aluminum alloy used
- the natural oxide layer
- Pre-treatment
- subsequent use
- mechanical, chemical, or environmental stress
- the right coating system
RIXAL® combines these factors into an application-specific surface solution.

Why Aluminum Requires Specialized Expertise
Not all aluminum is the same
RIXAL® is not a single coating process. RIXAL® represents the combined aluminum expertise of Rieger Metallveredlung: consulting, development, process engineering, and specially tailored surface solutions for aluminum. Whether it’s anodizing, direct nickel plating, combined coating systems, or multi-step surface solutions—the focus is not on the process alone, but on the technical requirements of the component.
What type of surface finish is appropriate? What load requirements must it meet? What alloy is being used? What function should the surface perform?
This is exactly where RIXAL® comes in.
For high-quality aluminum surfaces
When the default isn’t enough
Today, many aluminum components perform technical functions: they protect electronics, dissipate heat, resist corrosion, meet EMC requirements, or must withstand continuous mechanical stress. The surface is not merely a decorative detail, but a functional part of the component.
RIXAL® was developed to address precisely these requirements: as a center of expertise for aluminum surfaces that combines traditional processes with proprietary technologies and in-house R&D.
The goal is always to create a surface that suits the application.
Not too little.
Not unnecessarily much.
But just the right amount for the application.
