Salzgitter Mannesmann Research, using a two-point suspension arm as an example, shows how lightweight and cost-efficient chassis parts can be produced from steel materials. The developed component can be produced up to 54 % cheaper that the original aluminum suspension arm.

Steel Over Aluminum

In recent years, lightweight materials have increasingly taken over shares of classic in-car steel applications, for example forged aluminum for suspension arms in the premium mid-size segment. The current transition in the automotive industry, spearheaded by electrification, demands extending the range of electric vehicles, as well as cost savings to make financing more feasible. Recent studies suggest that it is less expensive to allow for a larger battery to increase the range and to forgo the extensive use of lightweight materials for cost reasons. Although this increases overall vehicle weight, researchers at the University of Duisburg-Essen, Germany, were able to demonstrate in studies [1]...
