Buy Refractory Chromite Sand – High-Quality Foundry & Casting Material
Product Overview
Refractory Chromite Sand is a premium-grade foundry material made from high-purity chromite ore (FeCr₂O₄). With excellent thermal stability, high melting point (1850°C), and superior resistance to metal penetration, it is widely used in steel casting, non-ferrous metal foundries, and refractory applications.
As a leading chromite sand supplier, we provide AFS 25-35 AFS25-30 AFS30-35 AFS35-40 AFS40-45 AFS40-50 AFS45-55 AFS45-50 AFS50-55 AFS55-60 AFS60-65 , and custom sizes to meet diverse industrial needs.
Key Features & Benefits
✅ High Refractoriness (1850°C+) – Ideal for high-temperature casting (steel, stainless steel, alloy steel).
✅ Low Thermal Expansion – Reduces casting defects like veining and cracking.
✅ Excellent Thermal Conductivity – Ensures uniform cooling and minimizes shrinkage porosity.
✅ Chemical Inertness – Resists slag and metal penetration, improving mold stability.
✅ High Density (4.5-4.8 g/cm³) – Enhances mold strength and reduces erosion.
