Import Chromite Sand Afs25/35 35/40 40/45 45/50 — Buy in wholesale FOB from Supplier in China

Zhengzhou Haixu Abrasives Co., Ltd imports chromite ore from South Africa, processes it by washing, drying, sieving, testing and packing in China, and then exports the sand from Chinese ports. The sand is offered in the AFS grades 25-35, 35-40, 40-45 and 45-50, with a chemical composition that meets a minimum of 46.0 % Cr2O3 and maximum limits for SiO2, FeO, CaO, MgO, Al2O3, P and S. Grain size conforms to the AFS specification, providing uniform particles for casting operations. The product is marketed as suitable for refractory and metal‑casting applications.

Typical industry values for chromite sand include a bulk density of about 2.7 t/m³, moisture below 0.5 %, and a low expansion rate of less than 0.02 % per 1000 °C. The listed chemical limits align with common specifications for high‑grade chromite sand used in demanding thermal environments. Packaging is standardised to 1‑metric‑tonne big bags, facilitating bulk handling. The supplier also lists additional AFS ranges from 25‑30 up to 60‑65, giving buyers flexibility to select particle sizes that match their mould designs.

Primary customers are foundries, steel producers and glass manufacturers that require thermally stable mould material. Zhengzhou Haixu provides flexible order quantities and can deliver under FOB or CIF terms from Chinese ports. Prospective buyers should request the full mill test report, confirm the exact grade and packaging, and discuss payment and delivery terms directly with the supplier.

Zhengzhou Haixu Abrasives Co., Ltd is located at Room 1903, Yaxing Times Plaza, Erqi District, Zhengzhou City, Henan Province, China. The company is classified as an imported‑tier supplier with a harbour‑level trust tier, indicating it principally sources raw chromite ore and resells it internationally. Its public response metrics show no recent replies, so prospective buyers should allow extra time for communication. The firm’s core activity is the processing of imported South African chromite ore through washing, drying, sieving and packaging for export.

The supplier does not list specific certifications, so buyers should request any relevant quality certificates or test reports. Shipping is arranged from Chinese ports on FOB or CIF basis, and the company can accommodate both small and large volume orders. As an importer, Zhengzhou Haixu does not own the mining operations but partners with sustainable mines, a claim reflected in its source description. Prospective customers are advised to obtain a mill test report to verify the chemical composition before finalising purchase.
