Green Diamond Foundry Sand
Green Diamond is available in ferrous and non-ferrous foundry grade sands.
Green Diamond is available in ferrous and non-ferrous foundry grade sands.
It is the ideal replacement for olivine and silica sands for molding and coremaking and it complies with the new proposed PEL limits for silica (it contains no crystalline silica). Due to low thermal expansion, Green Diamond foundry sand reduces the need for cushioning additives or combustibles.
Green Diamond foundry sand is offered in a wide range of screen distributions as well as special order pre-mulled sands with clay additives to meet your specific requirements. Ask our team about a sample and we can schedule a trial in your sand system.
Key Benefits:
Available in many AFS blends, including very fine sizes.
Ask us about our custom pre-mulled blends. Several sizes in-stock and ready to ship.
Green Diamond foundry sand is a reliable alternative to a silica or olivine green sand system. It’s mined and sourced in the United States and is silica free. The quality of the castings are superior when using Green Diamond.

Save time and eliminate the mixing process with pre-mulled Green Diamond foundry sand. Pre-mulled sand offers customer-driven sand recipes that offer a turn key solutions to foundry sand systems.
You pick the recipe, we’ll mull it and package it, so when it arrives to the foundry, it’s ready to be introduced to the sand system in high volumes, without the fear of compromising mold strengths.
Example: AFS 100 Green Diamond, 6% Southern Bentonite, 1.5% Water
Choose your recipe and let us mull the sand for you.
Green Diamond sand is mined and manufactured in the United States. It is a synthetic olivine sand that has been processed by melting, then granulated by quenching in water. It has the same advantages as natural olivine, but has no crystalline silica and low thermal expansion. This minimizes, or eliminates expansion defects.
It has a lower bulk density than traditional silica sand, which means you get more molds or cores per ton of sand, and it has a higher permeability. It has no loss on ignition, which means that it cannot give you pitting defects, or gas, as can be seen with some of the natural Olivines.
