Collaborative Project

Sustainable and cost-efficient
lightweight aluminum construction
for mobility applications

Lead Partner

Collaborative Project

In addition to energy-efficient drives, lightweight construction materials are the key for a reduction in environmental pollution and resource efficiency in mobility. To increase the lightweight construction potential in structural applications, high-strength Wrought aluminum alloys play a dominant role. When assessing resource efficiency and the CO2 reduction potential must not only include operational CO2 emissions be considered, but also the production-related emissions of the structural components, resource consumption and sustainability are assessed holistically. In this context The focus is on secondary aluminum alloys, as these alloys allow up to 95% of CO2 emissions to be saved compared to primary material.
