The first application of aluminium sheet on automobiles dates back to 1900’s Ford model T. But its development did not match the mass production in automotive until the recent 30 years. The prices of the petrol, environment regulations and the development of the aluminum rolling industry itself has different impacts during the journey. Nowadays the increased demand has been forcing significantly changes in aluminum rolling industry to supply the quantities and qualities of sheets that should the customer needs. 5xxx and 6xxx are the largest portion of alloys entered into the market. In contrast, 2xxx alloys were the key player in the early application but finally been kicked out.
In this talk, we review the key contribution of the rolling companies around the world who developed the 4 alloy families in 5xxx and 6xxx and worked with the automotive companies to make these alloy families successful. The key property requirements on two major groups of components in automobiles 1) structural and crash components and 2) body skins are introduced. By correlating the key microstructure, we can later have a better understanding the chances and challenges to develop the next generation of automotive sheet material and its forming processes. Finally, examples of the development of advanced alloys and forming processes worldwide are shown.
