Dry Silica sand
MOQ 100 Ton · Seller will confirm final rate
Foundry-grade silica sand is a high-purity sand primarily composed of silicon dioxide (SiO₂), typically exceeding 95% purity. It is characterized by its uniform grain size, rounded to sub-angular grain shape, and high refractoriness, making it ideal for metal casting applications. This sand offers excellent thermal stability, allowing it to withstand the high temperatures of molten metals without breaking down or fusing. Its controlled grain distribution ensures good permeability for gas escape while maintaining sufficient strength to form precise and smooth molds and cores. Low clay, iron, and alkali content help prevent casting defects and improve surface finish. Foundry silica sand is commonly used in: Green sand molding Core making Shell molding No-bake and resin-bonded systems It is typically light tan to white in color, free-flowing when dry, and compatible with a wide range of binders and additives. Due to its durability, it can often be reclaimed and reused multiple times in foundry operations.
