about this location
welcome to Faulquemont
The site in Faulquemont was founded in 1999 and belongs today to the Aalberts surface technologies family. The primary characteristic of our site in Faulquemont is to deliver the selective hard-anodizing treatment SELGA-COAT® to our customers. This process makes it possible to target precisely defined areas of mechanic components, with no need for prior masking.
Classic immersion surface treatments, either chemical or galvanic, generally prove their worth in numerous applications. These conventional procedures, however, are not well suited to treating components with highly complex geometries in a selective and targeted manner. In this field, and
particularly in the automotive industry, the selective SELGA-COAT® treatment offers an inexpensive alternative that doesn’t harm the environment.
“The partial hard anodizing of aluminum components is gaining more and more importance. A great advantage of the treatment is that only defined parts of the surface can be coated. This makes it unnecessary to mask the components before treatment or to mechanically rework them afterwards”.

the SELGA-COAT® process in detail
The electrolyte, one of the key elements in the SELGA-COAT® process, is also delivered to other companies who treat their components with SELGA-COAT ® machines in-house. Aalberts surface technologies Faulquemont sells SELGA-COAT® machines and integrates them directly into your production lines. The surface treatment, once integrated in the production process, eliminates typical manufacturing issues such as transport costs, late deliveries, temporary anti-corrosion protection, potential damage linked to handling, and lengthy production times.
Several SELGA-COAT® machines have been built and installed by Aalberts Surface Technologies SAS around the world: in Germany as well as in Brazil, China, India, Turkey and the Czech Republic. All SELGA-COAT ® machines work by passing electrolyte through closed circuits. The risk of the process being contaminated by possible impurities is much lower than with classical immersion processes. Given that the treatment is selective, the use of electrolyte is much lower, reducing the overall electrolyte consumption.industries where surface technology from Faulquemont is used
In Faulquemont we mainly treat aluminum components for the automotive industry in a selective manner with the SELGA-COAT® process, using machines specially designed for this kind of treatment. This innovative technology determines our daily routines at our Aalberts surface technologies plant in Faulquemont.
quality and know-how
A competitive advantage lies in the design of the treatment tools, developed and produced for each application, and in the definition of the treatment parameters. The components of the treatment tools are manufactured according to Aalberts surface technologies specifications, and the tools are fully assembled, attached to treatment machines, and initiated by Aalberts surface technologies.
SELGA-COAT ® is so well developed that treatment speeds of up to 10 times faster than those obtained in classic immersion baths can be reached. And the quality of the treatment is excellent as well:
- Very low treatment tolerances (up to ± 2 µm depending on the treatment)
- Very low roughness after treatment
- Good electrical insulation
- Excellent wear resistance
- Excellent corrosion resistance
areas of application
Our plant in Faulquemont works almost only for the automotive industry. The number of components treated may reach as many as 80,000 components per reference per year. The selective, hard-anodizing SELGA-COAT® treatment is used mainly in the following applications:
- Pump housings
- Piston engines
- Start & Stop system components
- Sandwich plates for automatic transmissions
- Steering gear boxes
Depending on the application, the layers can be produced via Cr6-containing* or Cr6-free electrolytes.
