In this study, Hydro Co-Extrusion Process of Al-Mn/Al-Si hybrid aluminum alloys prepared by electromagnetic duo-casting were investigated. Sleeve of the duo-casted billets is 3003 Al-Mn alloy and core is 4004 Al-Si alloy. It is expected hydrostatic stress during the HCE process enhances formability of materials and minimize any defects in extruded billets due to different material properties between two Al alloys. The duo-casted billet was extruded at temperature of 423K and with extrusion ratio of 5. The effect of the HCE on microstructure of the billet was investigated by an optical microscope.
