Zhengzhou Haixu Abrasives Co., Ltd. offers foundry chromite sand that is sourced from South African mines and supplied in AFS grades ranging from 25 to 55. The sand contains a minimum of 46 % Cr₂O₃ and low silica, providing strong chilling properties and low thermal expansion for demanding casting processes. It is packaged either in bulk bags or as loose bulk, allowing easy handling for high‑volume operations. The product is aimed at manufacturers that require consistent performance across large casting runs.
In the industry, chromite sand with 46 % Cr₂O₃ typically shows a bulk density of 3.1‑3.3 t/m³ and moisture below 0.4 %. Standard specifications require particle sizes that correspond to the selected AFS grade, for example about 0.15 mm for AFS 25 and up to 0.6 mm for AFS 55. The low silica content, usually ≤0.5 %, reduces slag formation and improves mould surface finish, which is essential for high‑precision castings.
Clients such as automotive, aerospace and heavy‑machinery foundries use this sand to achieve repeatable casting quality. Trade is normally arranged on FOB or CIF terms with payment via L/C or T/T, while minimum order quantities are negotiated per grade. Buyers should confirm the exact grade, packaging size and lead time with the supplier before finalising the purchase.

Importers should first obtain a current material test certificate that confirms chromium, silica and moisture levels, and consider requesting a sample to validate grain size and colour consistency before committing to a bulk order. Verifying the supplier’s harbour trust tier and confirming the registered address helps reduce commercial risk during the due‑diligence phase.
Logistics for the bulk sand are usually organised under FOB or CIF incoterms; prospective buyers need to agree on lead time, container loading plans and any freight forwarder requirements. Payment is typically arranged by L/C or T/T, and the exact terms should be documented in the purchase agreement.
Quality control commonly involves third‑party inspection agencies; buyers should arrange pre‑shipment testing for composition, moisture and refractoriness, and ensure the supplier provides the corresponding test reports and all necessary customs documentation for a smooth import process.
