Black Fused Alumina and Green Fused Alumina are two grades of high‑performance abrasive powders supplied by Ningxia Yongruidda Carbon Co., Ltd. The black grade contains Al2O3 at approximately 94‑95 % while the green grade reaches 97‑98 % purity. Both powders are produced by electric‑arc melting of quartz sand combined with petroleum coke or coal‑tar feedstock in a controlled furnace environment. The resulting grains are dense, low‑porosity and suitable for demanding grinding and cutting tasks.
In the abrasive market the black variant is valued for its toughness, whereas the green variant is prized for superior hardness and low wear. Typical particle sizes for fused alumina powders range from 80 µm to 300 µm, and bulk densities are around 1.6 g cm‑3. Moisture content is usually kept below 0.3 % to preserve flowability, and the powders often meet ASTM C722 specifications for fused alumina abrasives.
Key users include steel manufacturers, automotive component producers and precision‑machining workshops that require reliable abrasive media. Ningxia Yongruidda Carbon can ship the powders in 25 kg bags or 1‑ton drums, with CIF or FOB options available upon request. Prospective importers should confirm packaging dimensions, incoterms and payment conditions directly with the supplier before finalising the contract.

Ningxia Yongruidda Carbon Co., Ltd. is situated at No.742, Youyi East Street, Dawukou Zone, Shizuishan, Ningxia, China (postal code 753000). The company is listed under the harbour trust tier, indicating basic verification of its registration has been completed. No response data is recorded on the platform, so buyers should assess communication responsiveness directly.
The firm focuses on carbon‑based products and supplies both black fused alumina and green fused alumina for abrasive applications. Its export capacity includes handling the powders in 25 kg bulk bags or 1‑ton steel drums, serving international customers in the metalworking, automotive and construction sectors.
Black Fused Alumina and Green Fused Alumina are high-performance industrial abrasives used in grinding, cutting, and sandblasting operations. Black Fused Alumina offers excellent toughness and durability for heavy-duty applications, while Green Fused Alumina delivers superior hardness for precision grinding. Both materials are essential in steel, automotive, and metalworking industries, making them critical trade commodities for importers and distributors in the abrasives and refractories sector.

Importers should first obtain a certificate of analysis covering Al2O3 content, particle‑size distribution and moisture for the selected grade. Confirming the packaging type - 25 kg bag or 1‑ton drum - and its net weight helps plan handling at the receiving port. Requesting a small sample for laboratory testing of bulk density and hardness will reduce the risk of incompatibility with the intended abrasive process.
Ningxia Yongruidda Carbon can ship under CIF or FOB terms, but the exact incoterm must be agreed in the sales contract. Because lead‑time information is not published, buyers need to ask the supplier for a production schedule and expected dispatch date. Common payment methods include T/T in advance or a sight L/C; confirming the preferred method and any documentary requirements prevents payment delays.
A third‑party pre‑shipment inspection is recommended to verify that the powders meet the agreed specifications, especially Al2O3 purity and particle size. Required documentation includes the material safety data sheet, certificate of analysis and, where applicable, ASTM C722 test reports. Providing these records alongside the commercial invoice facilitates customs clearance and downstream quality
