Foundry sands

Grudzeń Las foundry silica sands are ideal for steel casting thanks to their high purity (SiO2 content above 99.2 %) and high temperature resistance. They are highly suitable for a high-quality casting surface on both grey iron and ductile iron, including non-ferrous metals. The oval shape of the grains permits reduction of the costs of expensive organic bonding agents (Cold-Box, Rezol CO2, furan, etc.).
