SILICA SANDS - We stock a wide variety of sub-angular and round grain sands available in 100# bags and 4000# palletainers. Round Grain sand has a reduced surface area, which significantly reduces the necessary bon or binder needed in green sand and no-bake systems.

CHROMITE - High-grade specialty sand occurs as magmatic segregations in ultrabasic igneous rocks that are mined and segregated. This sand is black in color and offers a very high heat transfer or a "chilling effect".

ZIRCON - 110 AFS Florida mined, round shaped sand, with high heat transfer.

WESTERN BENTONITE - (Sodium Montmorillonite) One of the basic clays used in the metal casting industry.

• Offers the highest hot and dry strengths
• Develops a high degree of plasticity or toughness
• The best clay for hot sand
• Very high degree of durability

SOUTHERN BENTONITE - (Calcium Montmorillonite) Offers several characteristics different from western bentonite and is predominately used in nonferrous applications.

• Develops the highest green strengths
• Mulls faster and produces the most flowable sand
• Lowest hot and dry strengths, and shakes-out freely

PREMIX - Additives are incorporated with the clays to created a preblended package. Preblends reduce material handling costs, save storage space, and increase mold production and consistency.

SEACOAL - A highly volatile low ash, low sulphur bituminous coal ground to various degrees of fineness. When mixed with molding sand and contacted by molten metal, the volatiles are released and give a quality to the casting called "peel". The sand does not stick to the casting, reducing cleaning cost and improving casting finish.
