The term 'procity' refers to the ability of a casting alloy to flow during pouring and filling the mold without forming air gaps or porosity. Sand casting typically exhibits higher procity due to its loose, porous nature that allows for better flow of molten metal. On the other hand, investment casting (lost-wax process) produces castings with lower procity but higher strength since it creates a more intricate and detailed casting with less porosity.
