Microstructure and mechanical properties of AlMg5Si2Mn alloy were compared under permanent mold casting and high pressure die casting. The microstructure was composed of primary α(Al) grains, eutectic phase and Fe-rich phase for both alloys. However, compared to permanent mold casting, the primary α(Al) grains were more finer and the Chinese script morphology of eutectic phase disappeared under high pressure die casting. Due to the large different between these two alloys, the ultimate tensile strength and elongation of AlMg5Si2Mn alloy under high pressure die casting increased by 32% and 24% (255 MPa and 8.8%), respectively, when compared to that of AlMg5Si2Mn alloy under permanent mold casting. Furthermore, the SIMA method was further applied to AlMg5Si2Mn alloy under high pressure die casting to prepare the semi-solid slurry. The results showed that AlMg5Si2Mn alloy solidified under high pressure die casting can be used as the raw material for semi-solid slurry.
