The Paths and Strategies for Increased Magnesium Applications in Vehicles

Abstract:

The use of magnesium in motor vehicles today and in future depends on numerous technical and economical factors, though the cost factor is essential. How might use of magnesium in vehicles develop, what prerequisites are necessary, what R&D efforts are required These questions will be addressed as follows based on component and project examples. The main focus of the current magnesium applications can be seen in the drive train and in the interior. In the short term, these applications will be further expanded: doubling the amount is feasible. This will be supported by the currently developed Mg alloys with extended application potential (creep resistance). Mg components in the body, Mg-sheets and Mg-extrusions applications will appear initially in niche-market and premium vehicles. This can prepare the way for and eventually lead to greater use of Mg in volume-production models as part of a multi-material design concept. The essential prerequisites for such increased use of magnesium will be discussed.
