Abstract: The automotive industry faces major challenges as environmental regulations become increasingly stringent and demand increases for low emission vehicles without compromised performance or safety. Well-designed aluminium alloys provide attractive light-weight solutions to these challenges and therefore continue to experience growth in automotive applications. This contribution provides an overview of how foundry, extruded and rolled products based on Rio Tinto low-CO2 primary aluminium are addressing these challenges. The production of high quality automotive sheet commences with optimised rolling slabs. In terms of foundry alloys, property requirements for various structural and power train applications are discussed and solutions are presented for products including wheels, shock towers, cylinder heads and rotors for electrical motors. For extrusions, there is growing demand for alloys with higher strength or improved crash performance, so solutions to improve strength, ductility and energy absorption capabilities are discussed. Due to the demanding deformation, joining and fracture conditions encountered in many automotive structural applications, specific tests such as VDA bend testing are becoming increasingly important for both extrusion and foundry alloys. Finally, there are also important processing and cost considerations, so adequate castability and downstream processability must be maintained.
