Chromite sand 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 is fine ground powder processed from natural chromite ore, mainly composed of iron chromium oxide. It features high refractoriness, low thermal expansion, excellent chemical stability and strong chilling effect, widely used in foundry and refractory industries.

DESCRIPTION: Chromite Sand is a naturally occurring spinel consisting primarily of the oxides of chrome and iron. It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.

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.
