Research Projects
A vital pillar for us in forming technology is the material and process qualification. In the competition among materials for efficient, lightweight construction, new concepts for high-strength steels or light metals (e.g., aluminum or magnesium) are continuously emerging. This research focus requires a combination of basic research and practical transfer projects.
