Systems and methods for making aluminum alloy products are described including those that decrease the tendency for hot tearing or shrinkage porosity to occur during casting by introducing forced convection during the casting process. The forced convection may result in formation of high circularity grains during the solidification process, thereby increasing the permeability of the liquid aluminum alloy and decreasing the tendency for hot tearing or shrinkage porosity to occur.
