Foundry sands for metal castings

 

Due to its high thermal-mechanical stability and its favourable grain shape and surface structure crystal quartz sand from Schlingmeier is an outstanding silica for molds and cores for metal castings.

 

The following table shows selected grades which are preferably used in foundries. All dry sands (T)  can be supplied as blended grades. Please let us know your favourite grain size distribution.
