Introduction to Foundry Sand | American Foundry Society
Introduction to Foundry Sand What is foundry sand? Most metalcasting sand (FS) is high quality silica sand with uniform physical characteristics. It is a byproduct of the ferrous and nonferrous metal casting industry, where sand has been used for centuries as a molding material because of its unique engineering properties.
Silica Statistics and Information - USGS.gov
Silica Statistics and Information Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO 2 ) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses.
