chromite sand reduces cleaning and finishing costs, improves casting yield, and contributes to producing a superior, defect-free hammer ready for heat treatment and service.

chromite flour has several uses, its main application is unquestionably as the critical ingredient in refractory coatings for foundry molds and cores, where it is essential for producing high-quality, complex, and clean steel castings.

chromite sand superior thermal stability, inertness, and durability justify its use in critical industrial processes

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.
