FARMINGTON HILLS, MI—Alcoa Inc. says it has solved one of the biggest wrinkles automakers wrestle with when stamping aluminum body panels: formability. The company has developed a new manufacturing process that produces aluminum sheet that is 40 percent more formable than current aluminum alloys.
Aluminum will play a growing role in the automotive industry in the years ahead. In fact, aluminum use in vehicles is projected to double by 2025, as automakers continue to roll out a wide variety of lighter weight models.
