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.).
This is a fireproof material (more than 1800 °C) whose high temperature resistance makes it ideal for places exposed to the high heat of casting, and not only of steel. Compared to silica sand, it differs in its higher cooling effect, resistance to penetration, and lower thermal expansion. However, its relative density is higher. It also finds application in glass production where glass is tinted, as well as in ceramics.
This is round, thermally treated steel shot with a fine homogeneous structure of tempered martensite. Our production is outsourced to a Russian manufacturer, who guarantees our technical parameters, such as hardness of 450 – 560 HV, porosity under 10% and density of at least 7200 kg/m3. The quality of our steel shot, including the packaging, is very high and conforms to the SAE J 444 standard. The material is perfect for most applications using casting wheels for blasting.
