What is foundry sand? - Solex
2020-5-7 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.

Foundry Sand: Life of a Casting Reliance Foundry
Ferrous foundries (those dealing with iron and steel) usually use silica sand, sometimes known as quartz sand. Silica sand has long been used in core making, so switching to using the same aggregate throughout the casting process has made the process of managing foundry supplies easier. Silica sand is the most commonly used type of foundry sand.
