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.
