FOUNDRY COATING CHROMITE SAND APPLICATIONS
Chromite Sand for foundry paint
Chromite sand is ideal for high-duty grey iron and steel foundries as core and mold making sand.
The high thermal conductivity of chromite sand gives it good chilling properties; low thermal expansion gives rise to good dimensional stability.
