Aluminium surface treatments for mobility
How do we increase wear resistance and lifespan of aluminium profiles in EVs and mobility solutions?
More and more (e‑mobility) applications require lightweight and durable aluminium components. Think of connectors, heat exchangers, rails, and interior parts. These components are exposed to conditions such as mechanical load, moisture, dirt, and chemicals. At Mifa Surface Treatment, we guide our customers step by step in selecting the right treatment for wear resistance, corrosion protection, and service life.
Perform beyond the surface.
When which layer? Choose based on application and requirements
In surface treatments for mobility applications, we always make choices based on the alloy, load, and environment of the component. Our engineers always look beyond the surface. Mifa also uses test coatings to ensure that the selected coating delivers the optimal result. This way, you can be certain that your profile or component is lightweight, dimensionally stable, and corrosion‑resistant.
Within mobility applications, the following factors often play an important role:
- Optical consistency in series (color/gloss).
- Wear resistance for moving parts such as guides or couplings.
- Cr6‑free and REACH‑compliant.
- Electrical or thermal requirements, low friction, or high chemical resistance.
- Coatings must be “FDA approved.”

The Surface Selector
Choosing the right aluminium coating starts with asking the right questions. We’ll work with you to identify the application and desired properties to determine the best surface treatment.
Discover your options using our Surface Selector and receive tailored advice.
Do you require wear resistance, corrosion protection, a Cr6-free alternative, or do you need to meet specific visual requirements? We’ll guide you to the right choice.

Advantages of the right surface treatments for mobility applications
The right surface treatment provides increased wear resistance, reduced maintenance, and extended service life. In addition, there are several other advantages:
- Corrosion resistance meets the MIL‑DTL‑5541 standard and is tested on Cr6‑free layers.
- Color consistency in series production is ensured, especially for visible parts and interior elements. Both mechanical and chemical pre‑treatments are possible, as well as a wide range of color options.
- No dimensional deviations occur during the anodizing process, even with thin‑walled profiles.
- A test coating allows the validation process to be completed quickly and efficiently.
- The layer build‑up is carefully tailored to critical fitting surfaces.
-
What is the best coating for aluminium in EVs?
That depends on the application. For wear‑sensitive components, hard anodizing or TUFRAM® is often suitable. For aesthetic visible parts, we recommend colored anodizing.
-
Can Mifa anodize 6xxx or 7xxx alloys?
Yes. We have extensive experience with all alloys.
-
Are your processes REACH‑compliant?
Our processes are Cr6‑free and REACH/ROHS‑compliant. Documentation aligns with OEM/tier specifications and can be provided in PPAP format if desired.
-
How does the coating affect dimensional accuracy?
We design for dimensional stability and take coating thickness and roughness into account. A deviation of <10 μm is achievable and is reported.
-
How do you ensure dimensional accuracy during anodizing?
We ensure maximum dimensional stability by designing with careful consideration for layer growth (both inward and outward), surface roughness, and tolerances. Thanks to fixed process programs in our fully automated line, all parameters are strictly controlled, allowing us to maintain a dimensional deviation of <10 μm.
Part of Aalberts
Mifa Aluminium is part of Aalberts, a publicly listed technology company. This allows us to combine our own expertise in extrusion and surface treatment with the specialized knowledge of Aalberts Surface Technologies. Treatments we do not have in‑house can therefore be outsourced within the group. This ensures you always receive the optimal end result, with the convenience of a single point of contact.
