Chromite Foundry Sand Afs25/30/35/40/45/50/55
Chromite foundry sand in AFS grades 25 through 55 from Zhengzhou Haixu Abrasives Co., Ltd. is a precision-grade refractory material sourced from South African deposits, designed for high-temperature steel casting. Each AFS grade corresponds to a specific mesh size range, enabling foundries to select sand for fine detail molds or coarse cores. The material features low thermal expansion and high thermal conductivity, critical for minimizing casting defects.
The sand is composed of FeO·Cr2O3 with low silica content, reducing veining and metal penetration. Grain shape is naturally subangular, promoting interlocking and mold stability. The supplier indicates the product is processed to remove fines and meet AFS grading standards, which define particle size distributions for consistent mold performance. This distinguishes it from generic chromite sands that lack standardized grading.
This product is used by steel foundries producing engine blocks, turbine components, and heavy machinery parts. Buyers typically order by AFS grade, with common selections being AFS 35 for medium molds and AFS 50 for thin-wall castings. Packaging is in bulk bags or loose form. Trade terms are available on request, but MOQ and lead time are not specified and must be confirmed directly.
| AFS grain size grades | 25, 30, 35, 40, 45, 50, 55 - each corresponds to a standard mesh size range per AFS standards |
| Chemical composition | FeO·Cr2O3, sourced from South African chromite, Cr2O3 content typically 45-50% |
| Silica content | Low, typically below 8%, to reduce metal-slag reactions |
| Bulk density | Typical range 2.9 to 3.1 g/cm³ for South African chromite sand |
| Thermal expansion | Low, standard for chromite sands used in steel foundries |
| Refractoriness | Above 1800°C, standard for high-temperature casting applications |
| Particle shape | Subangular, typical for natural chromite processed for foundry use |
| Moisture content | Typically below 0.5%, critical for mold integrity |
| Packaging | Bulk bags or loose form, standard for industrial mineral shipment |
| Origin | South African chromite ore, processed in China |

Sourcing Chromite Foundry Sand Afs25/30/35/40/45/50/55 from Zhengzhou Haixu Abrasives Co., Ltd. - China Import Guide
Before ordering AFS-grade chromite sand from Zhengzhou Haixu, confirm the exact AFS grade and its corresponding mesh size range for your application. Request a batch-specific sieve analysis and chemical assay to verify Cr2O3 content and silica levels. Ensure the product matches your foundry’s historical sand specifications to avoid casting defects or process adjustments.
Confirm Incoterms, lead time, and packaging form - bulk bags or loose shipment - with the supplier. Lead time is not stated; expect 25-40 days from China port. Verify if the supplier provides export documentation including commercial invoice, packing list, and bill of lading. Payment terms are not specified; buyers should negotiate against standard LC or T/T terms.
Upon arrival, inspect packaging for moisture damage and perform a quick sieve test to validate grain size. Test moisture content with a loss-on-drying method and check for foreign matter. Retain a sample from each shipment for traceability. Request a certificate of analysis for each batch and compare it to your internal quality records.
