Premium Chromite Sand — High Thermal Resistance for Demanding Castings
Prevent sand fusion and core breakage in thin-section steel and iron castings. Chromite sand's high density and superior softening point deliver consistent quality where silica fails.
Get a QuoteWhen silica sand fuses under high heat
Steel castings poured at extreme temperatures cause standard silica sand to soften, fuse, and adhere to the casting surface — destroying surface finish and causing scrapped parts. The result: burnt-on sand, metal penetration, and rework costs that compound with every pour.
Thin-section cores face a separate but related failure mode: breakage under thermal shock. When the core cannot dissipate heat fast enough, it crumbles — collapsing the water jacket, hydraulic passage, or internal cavity it was meant to form.
Chromite sand solves both problems by providing a significantly higher softening point and superior heat conductivity. Where silica gives up, chromite holds — delivering clean surfaces and intact cores even in the most demanding ferrous castings.
High Softening Point
Resists fusion up to extreme steel pouring temperatures
Better Heat Conduction
Faster heat dissipation through core, controlled solidification
High Density
Better bonding strength with organic and inorganic binders
Prevents Fusion
Eliminates metal penetration and sand fusion defects
Where chromite sand performs
Chromite sand is the go-to solution when silica fusion and core failure create persistent quality problems in ferrous casting production.
Steel & Alloy Steel Castings
Where silica fusion and metal penetration are persistent defects. Chromite's high refractoriness eliminates the root cause.
Thin-Section Cores
Water jacket cores, hydraulic passages with narrow cross-sections — where thermal shock destroys silica cores before the metal solidifies.
High-Manganese Steel
Castings requiring chilling and controlled solidification to achieve target hardness and wear-resistance properties.
Ductile Iron
Heavy section castings where sand fusion is a recurring risk at high-iron pouring temperatures and extended solidification times.
Investment Casting Cores
High surface finish requirement with extreme temperature exposure — chromite's dimensional stability prevents core distortion.
Prototype & Low-Volume Production
Where a full silica changeover isn't justified. Blend chromite into problem areas only, targeting defect elimination with minimal cost impact.
