Foundry sand is clean, uniformly sized, high quality silica sand, used in foundry casting processes. The sand is bonded to form molds or patterns used for ferrous (iron and steel) and non-ferrous (copper, aluminum, brass) metal castings. Shake-out sand from completed metal casting are often reclaimed back into the foundry sand process.

Fine foundry aggregate– or the silica grain size, can often be adjusted by sifting through screen-sized or washing out fines, as is sometimes done at sand quarries. Quality control specifications can usually be met by one of the methods of fines-control; however, they may introduce additional costs.

tool, the casting design cycle may be shortened and overall production efficiency may be increased. Burn-on is a casting defect where liquid metal fills the voids in the sand mold or core without displacing the grains, causing sand, mold wash, or oxides to adhere to the casting surface.

Other additives for green sand casting. Moisture is an important component in all green sand casting. Water is generally added at 2-5% of the weight of the mixture. The hydrostatic bonds between water molecules strengthen the sand: it is these bonds that build sandcastles from wet sand on the beach, and the same forces are at work in the foundry.

The spent foundry sand is either recycled in non-foundry applications or landfilled. In 2007, the American Foundry Society estimated (PDF) (5 pp, 1.94 , About PDF) that less than 30 percent of the 10 million tons of spent foundry sands generated annually are recycled. EPA believes a greater percentage of spent foundry sand can be safely and ...
