Lightweighting with iron

Grede throws advanced ultra-high-strength cast ductile iron into the lightweight-materials ring for commercial-vehicle chassis and powertrain applications.

Cost-competitive lightweight materials are a significant and relative objective for commercial-vehicle (CV) manufacturers and component suppliers. This focus has expanded significantly in all areas of CV segments, impacting both powertrain and chassis applications. The primary challenge to determine the optimal lightweight material is multifaceted in an effort to meet all imperative load criteria, while simultaneously providing mass savings in a globally scalable, cost-competitive solution.

Grede Holdings presents a comparative analysis of lightweight material options in both strength and cost unit values. Further comparisons qualify the improved value performance of advanced ultra-high-strength cast ductile iron materials such as the SiboDur grades that provide a lightweight and cost-competitive solution vs. the traditional nonferrous cast aluminum materials.
