The application of Al parts in passenger car has been increasing for the last decade, which gives many advantages such as better fuel efficiency, driving performance and safety. Control arm is one of the most preferably substituted parts from steel into Al alloys among numerous automotive parts. Currently, both wrought and cast Al alloys can find the application for control arm in passenger car. The balance between performance and cost determines a material as well as a fabrication process for a particular part model. In the present study, comparison among various processing techniques has been carried out to build up a data base for Al control arm fabrication.
