Black silicon carbide for abrasives (F46) from Henan Sicheng Co., Ltd. is manufactured in electric resistance furnaces from quartz sand and petroleum coke, resulting in a material with a microhardness of 2800 - 3300 kg/mm². The listing specifies exact chemical composition thresholds: SiC ≥99% for F8 - F360, with free carbon ≤0.2% and Fe2O3 ≤0.2%. F46 is a medium-grade abrasive suitable for general-purpose grinding.
This material is produced to meet FEPA, GB, and JIS standards, as stated in the supplier profile. It is used in bonded abrasives such as grinding wheels and in coated abrasives like sandpaper. The product is also suitable for abrasive blasting and refractory applications. Unlike some suppliers, Henan Sicheng provides detailed chemical limits for each F-grade, indicating a controlled production process.
Buyers in the metalworking, ceramics, and stone processing industries commonly source this material for surface finishing and stock removal. Packaging is in 25kg PVC bags with 1 metric ton big bags available. The supplier has exported to Europe, the USA, India, and Japan. MOQ, lead time, and Incoterms are not listed and must be confirmed directly.

Verify the F46 particle size distribution with a sieve analysis report before shipment. Confirm that the SiC content, free carbon, and iron oxide levels match the stated thresholds. Request a sample for performance testing in your grinding wheel formulation. Do not accept generic certificates - demand lab-specific data with accredited signatures.
Confirm packaging type, net weight per bag, and container loading method. Ask for Incoterms such as FOB Qingdao or CIF Mumbai, and clarify payment terms like T/T 30% advance. Lead time is not stated; request a production timeline and shipping schedule. Ensure the supplier provides export documentation including commercial invoice, packing list, and certificate of origin.
Conduct a pre-shipment inspection for moisture content, particle size consistency, and absence of foreign matter. Use a sieve stack to validate F46 grading. Check for clumping or discoloration that may indicate contamination. Retain a sample from each batch for post-delivery testing. Request a quality control certificate signed by the supplier’s lab with date and batch ID.
