从China供应商批发进口Afs40-45 Chromite Sand Afs40-45 — FOB条款

This AFS40-45 chromite sand is processed by Zhengzhou Haixu Abrasives Co., Ltd. from South African chromite ore, with a minimum Cr2O3 content of 46.0% and controlled impurities such as SiO2 at 1.0% max and FeO at 26.5% max. The AFS 40-45 grain size is coarser than the AFS25-30 grade, offering higher permeability and suitability for larger or more complex castings where gas escape is a priority.

The chemical composition includes Al2O3 at 15.5% max and MgO at 10.0% max, which contribute to the sand’s thermal stability and resistance to chemical reactions during casting. Chromite sand is widely used in foundries for its ability to withstand high temperatures and maintain dimensional stability, making it ideal for ferrous and non-ferrous metal casting. Typical industry applications for this grade include heavy-section castings and cores requiring robust permeability.

Buyers in the foundry and steel industries use this sand for applications such as large molds and cores in iron and steel casting. It is packed in 1MT big bags for export from China ports. The supplier’s processing includes washing, drying, sieving, and testing to ensure the sand meets the specified chemical and physical properties. Importers should confirm the grain size distribution and packaging suitability for their specific casting needs.

Zhengzhou Haixu Abrasives Co., Ltd. is headquartered in Zhengzhou, Henan Province, China, with its office at Room 1903, Yaxing Times Plaza, Erqi District. The company specializes in importing chromite ore from South Africa and processing it into foundry-grade sand for export. Its operations are focused on supplying quality chromite sand to international markets, particularly for foundry and abrasive applications.

The supplier’s trust tier is harbor, and its response rate is currently 0.00%, indicating limited engagement via the platform. The company’s processing steps include washing, drying, sieving, and testing to ensure the chromite sand meets the required specifications. Buyers are advised to verify the supplier’s current response capacity and quality control measures directly, as no additional certifications or performance data are provided.
