In collaboration with Metalsa, a global supplier of light and commercial vehicle and chassis structures, Alcoa Aerospace Transportation & Industrial Products unveiled a development-phase, all-aluminum commercial truck frame at the 2015 Mid-America Trucking Show. The aluminum alternative will reduce heavy-duty truck weight by over 40 percent compared to steel frames, saving nearly 900 lb. per vehicle. In addition to increasing fuel efficiency and payload, company engineers note, the aluminum frame’s increased stiffness will double rigidity, enabling a smoother ride. Higher corrosion resistance, compared to a steel frame, can extend a vehicle’s service life.
