The semi-solid forming (SSF) of aluminum alloys offers many advantages overconventional casting processes. Nevertheless, the semi-solid forming is still far from its fullcommercial potential and mainly used in specific niche markets. The market positioning requiressimple, low cost, and versatile SSF processes that are capable of processing a wide range of alloycomposition including wrought alloy compositions. However, wrought alloys must be adapted toobtain the desired semi-solid processing ability and proper mechanical properties. The processing ofthese attractive alloys with the SEED process offers the possibility to better target specificapplications and customers’ needs. In the present paper, the alloy development of AA-6061 aimingto minimize the hot tearing propensity during forming process is reported. An overview of theindustrial SEED process used to produce the semi-solid AA-6061 feedstock is presented. Themechanical properties of the cast parts subjected to a specific heat treatment were evaluated. As partof the joint effort between Alcan International Limited and the National Research Council ofCanada (NRC), the fatigue results obtained from the semi-solid AA-6061 die cast parts will be alsoreported
