Import Chrome Ore Sand For Sand Moulding — Buy in wholesale FOB from Supplier in China

Chrome Ore Sand For Sand Moulding is a refractory material derived from crushed and washed South African chrome ore, processed through spiral concentrators, drying, and precision screening. The product meets specific chemical limits: Cr2O3 at 46.0% minimum, SiO2 below 1.0%, FeO under 26.5%, and P and S each capped at 0.003%. Physical properties include a bulk density of 2.5 to 3.0 g/cm³, specific gravity between 4.0 and 4.8 g/cm³, and a neutral pH range of 7 to 9. The sintering point is 1600°C and melting temperature reaches 2180°C, making it suitable for high-temperature foundry applications.

This sand is available in seven standard grain sizes: AFS30-35, AFS35-40, AFS40-45, AFS45-50, AFS50-55, AFS55-60, and AFS60-65, each screened for uniformity. The material is free of clay and foreign matter, with soil content under 0.1% and acid consumption limited to 2 mL maximum. These characteristics align with industry standards for foundry sands requiring high thermal stability and low expansion. The Cr/Fe ratio of 1.55:1 ensures consistent chromite content, critical for core and mold integrity under casting conditions.

Foundries producing steel, stainless steel, and high-alloy castings use this sand for its resistance to thermal shock and minimal chemical interaction with molten metal. Buyers include medium to large-scale casting manufacturers in Asia, Europe, and North America seeking reliable refractory fillers. Packaging is typically in 25 kg bags or bulk flexitanks, with standard lead times of 15 to 25 days after order confirmation. Incoterms are usually FOB Qingdao or CIF destination, subject to negotiation. Buyers should confirm the exact AFS grade and moisture content before shipment.
