Application

Natural chrome ore is used as form sand in foundry applications. 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.
