chromite sand used in molds for automotive castings
Chromite Sand in Automotive Casting Molds: Properties, Applications, and Benefits Chromite sand (FeCr₂O₄) is a refractory mineral sand widely used in foundries, particularly for automotive casting molds and cores. Its high melting point, thermal stability, and resistance to metal penetration make it ideal for demanding casting processes, such as engine blocks, cylinder heads, brake components, and transmission parts.
