This AFS25-30 chromite filling sand is sourced from South African chromite ore, processed and exported from China ports by Zhengzhou Haixu Abrasives Co., Ltd. The sand meets a minimum Cr2O3 content of 46.0%, with controlled impurities including SiO2 at 1.0% max, FeO at 26.5% max, and trace elements like phosphorus and sulfur capped at 0.003% max. Its AFS 25-30 grain size distribution is tailored for foundry applications requiring fine to medium refractoriness and thermal stability.
The material composition is balanced for foundry use, with Al2O3 at 15.5% max and MgO at 10.0% max, ensuring consistent performance in high-temperature metal casting. Chromite sand is valued in ferrous and non-ferrous foundries for its ability to resist thermal shock and maintain dimensional stability in molds and cores. Typical industry standards for chromite sand include AFS grain fineness numbers ranging from 25 to 65, with this grade falling in the finer spectrum for precision casting.
Buyers in the foundry, steel, and abrasives industries use this sand for applications such as mold and core making in iron, steel, and copper casting. It is packed in 1MT big bags for bulk handling and export from China ports. The supplier’s processing steps include washing, drying, sieving, and testing to ensure compliance with the specified chemical and physical properties. Importers should confirm packaging integrity and certification for their specific use cases.

Before ordering, verify the supplier’s current stock availability and the exact AFS grain size distribution for your application. Confirm that the Cr2O3 content and impurity levels meet your foundry’s specific requirements, as these directly impact casting quality and mold performance. Request a recent certificate of analysis to ensure consistency with the listed specifications.
Discuss logistics details such as port of loading, lead time for processing and export, and Incoterms (e.g., FOB or CIF) to clarify responsibilities for shipping and insurance. Packaging should be confirmed as 1MT big bags or alternative options if required. Payment terms, such as TT or LC, should also be agreed upon to avoid delays in transit or clearance.
Conduct quality checks upon receipt, including visual inspection for grain size uniformity and testing for chemical composition and refractoriness. Inspect packaging integrity to prevent contamination during transport. Request documentation such as the material safety data sheet (MSDS) and test reports to ensure compliance with your foundry’s standards and regulatory requirements.
