 Foundry Sand


Mined and manufactured to the high standards of U.S. Silica's Quality System Air sized and blended to meet the most demanding foundry specification.

In foundry application, the medium grades: #49, #56, #63 offer high permeability due to excellent fines control and are ideal for most core and molding applications in iron, steel and non-ferrous foundries. They also offer high strength in all binder systems.

The finer grades: F 71 consist of rounded to sub-angular grains, which provide high strength and excellent permeability. They achieve superior casting finishes in all binder systems and metals.
