        Aluminum | Raw to Ready: Bentley

        This clip from Raw to Ready: Bentley focuses on how the automotive industry was revolutionized from heavy cast iron for engine blocks to lighter aluminum. W.O. Bentley experimented with aluminum and was commissioned by the Allied forces to create lighter plane engines. By the 1950s, silicon and magnesium were incorporated into the aluminum alloy to create a stronger lightweight metal that is still used on Bentley V8 engine blocks today.
