What is foundry sand? Solex Thermal Sciences

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 nonferrous (copper, aluminum, brass) metal castings. Shakeout sand from completed metal casting are often reclaimed back into the foundry sand process.
