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.
