For more than four decades, Constellium has been transforming semi-finished products into prefabricated components.
Our plant in Nuits-Saint-Georges (France) has three anodizing lines capable of treating profiles of up to 8.4 meters long.
Anodizing is a specific surface treatment for aluminium whereby an electrolytic process is used to create a uniform and resistant surface layer of aluminium oxide. This coating gives a very attractive satin finish to the product and can be performed with an optional coloring process.
The complex anodizing process involves a series of soaking tanks and successive rinsing processes. It consists of four main process steps:
Our anodizing process complies with the Qualanod quality standards for anodic oxide coatings. Our anodizing lines are capable of treating profiles up to 7 meters long.
In addition to extrusion and surface treatment operations, our machining workshops and network of sub-contractors offer a wide variety of finishing services.
By delivering parts that are in an advanced stage of finishing or ready-to-use parts, we help customers optimize their own production processes and cycle times.
Constellium’s soft alloys plants in Germany offer expertise in finishing. These include:
Other options are available on request, provided either in-house or with long-standing and experienced local partners.
In addition to manufacturing extrusions, Constellium’s soft alloys plants have more than 40 years’ experience in transforming semi-finished products into prefabricated components.
