A Comparative Study on the Production of a Hat Profile by Roll Forming and Stamping

Lightweight design using high‐strength aluminum alloys has gained importance due to the continuing need for weight reduction and increasing crash safety requirements in automotive industry. There are various manufacturing processes available processing alloys. Herein, production of parts by roll forming stamping based on example an AA7075‐T6 hat profile is compared. Roll represents a continuous process, while discontinuous process. Different process routes (T6, W‐Temper O) as well W‐Temper, O hot forming) focus investigation. Fundamental differences tempering condition observed criteria choice route presented. The temperature‐supported improve poor cold formability AA7075 alloy thus enhance window. Potential offered both applying tailored properties achieved through targeted quenching.
