January 2021 Aluminum expected to accelerate worldwide adoption of electric and self-driving vehicles Material takes on an ever-widening role in tomorrow’s vehicles For more than a decade, concerns about fuel efficiency have been encouraging OEMS to replace steel with aluminum on vehicle bodies, doors, trunks, hoods, bumpers, crash boxes, brakes, cables and wheels. With the advent of electric and autonomous vehicles, OEMs worldwide are discovering new uses for aluminum. The need for battery casings and heat exchangers in electric vehicles, combined with autonomous vehicles’ demands for high visibility and structural integrity, is expected to exponentially increase the use of sheet aluminum in tomorrow’s cars, trucks and buses. Supporting the transition to battery-powered vehicles Four major design challenges confront OEMs in their transition to electric vehicles. Extending vehicle range Improving battery and passenger safety Increasing passenger comfort Optimizing cooling systems for lithium-ion batteries The substitution of sheet aluminum for steel helps resolve OEM concerns.
