Metal Casting Sand Chromite Sand
Chromite sand is a high-performance specialty foundry sand mainly composed of FeCr₂O₄ (chromium iron oxide). It is widely used in steel casting, alloy steel and high-temperature alloy casting due to its high refractoriness, high thermal conductivity, low thermal expansion and excellent anti‑penetration properties.
