Foundry sands for use in manufacturing, CDE Global

Foundry Sands. Foundry sand (also known as casting sand) consists primarily of clean, uniformly sized, high-quality silica sand that is bonded to form moulds for ferrous (iron and steel) and nonferrous (copper, aluminium, brass) metal castings. The most common casting process used in the foundry industry is the sand cast system.
