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.

chromite powder for foundry coating

Chromite powder is a cost-effective, high-performance refractory for foundry coatings, particularly suited for ferrous and high-alloy castings. Its balanced properties (thermal stability, erosion resistance, and moderate cost) make it a versatile alternative to zircon in many applications. Proper selection of particle size, purity, and binder systems is critical to optimize casting quality.

chromite powder used as foundry casting

hromite powder is widely used in foundry coatings (also called mold washes or refractory coatings) to improve the surface quality of metal castings. 1. Role of Chromite in Foundry Coatings Chromite powder (FeCr₂O₄) is applied as a refractory coating on sand molds and cores to: Prevent metal penetration (burn-on defects). Reduce sand fusion (sand sticking to the casting). Improve surface finish (smoother castings). Withstand high
