Chromite Sand is a naturally occurring mineral consisting primarily of the oxides of chrome and iron. Its properties enable the material to be used in high duty grey iron and steel foundries as a core and mould making sand. Its high thermal conductivity gives it good chilling properties whilst its low thermal expansion gives rise to good dimensional stability. Its basicity being close to neutral allows the use of a wide range of resin bonding systems and inorganic binders.

Chromite sand advantages:
Good thermal conductivity
Good resistance to thermal shock
Excellent resistance to metal penetration or burn-on
Resists slag attack
High dimensional stability
