Researchers introduce a speedier manufacturing process for stronger aluminum alloys
When Ford began building the F-150 with mostly aluminum bodies in 2014, the popular truck slimmed down by about 700 pounds. That change was designed to improve gas mileage and save money at the fuel pump. Even more weight could be saved by using advanced aluminum alloys for components such as roof rails, cross beams, subframes, and other structural parts. But that hasn't happened because these alloys are expensive, due in part to their slow manufacturing rates using conventional extrusion.
