Abstract：Systematic change of riser size together with variation of thickness and length of A201 aluminum alloy plate castings were studied to investigate the correlation between mechanical properties and porosity content. The molds with end chill for plate castings were made of 100% chromite sand by CO₂ process. If soundness throughout the whole plate casting has to be guaranteed，the riser diameter should be proper design to the dimension of the plate. The tensile strength and elongation of A201 aluminum alloy plate casting is governed by riser diameter，thickness，and length of the plate.
