Material and part production choices can significantly influence the climate impacts and energy demands of automotive manufacturing. As vehicle producers consider new manufacturing strategies, understanding these trade-offs is essential for informed decisions about materials, production processes, and emissions reduction.

This steelTalk compares conventional stamped steel solutions with aluminium high-pressure die casting (HPDC) and mega-castings. The discussion draws on research and a case study recently published in the SAE International Journal of Sustainable Transportation, Energy, Environment, & Policy.

The analysis considers how different automotive part production routes affect life cycle global warming potential (GWP) and energy demand, including the implications of replacing conventional stamped steel components with large aluminium mega-castings.

Russ Balzer of WorldAutoSteel and Brandie M. Sebastian, LCACP, of Brandie Sebastian Consulting LLC will explore what these findings mean for life cycle assessment practitioners, automotive OEMs, policymakers, and others evaluating material and manufacturing choices.
