Soundness The performance of spent foundry sands in soundness tests depends on the amount of clay binder materials present in the spent foundry sand, the amount of agglomeration of the fines, and the coating on the individual particles. The greater amount of clay binder or agglomeration, or the thicker the coatings, the higher the soundness loss.

Mar 25, 2014How fine the sand is depends on the particular metal you are pouring. For cast iron, you want a coarser mesh sand, say in the 60 mesh range or so. For aluminum, a 50/50 mix of 90 and 120 mesh sand is said to give the best balance in surface finish and porosity. For brass/bronze, this is where you need the finer mesh sand, 120 mesh and up.
