Rs Sub-white Fused Alumina is a premium corundum‑based abrasive grain produced from high‑purity alumina bauxite. The material is chemically Al₂O₃ and is manufactured in an electric arc furnace at temperatures above 2300 °C, followed by an extended refining stage. The supplier describes the product as a high‑performance alternative to white fused alumina and tabular alumina, offering superior hardness and thermal stability. Grain morphology is available as sand (Barmac plastic) and micropowder (acid washed) with low apparent porosity.
In the abrasive industry, sub‑white fused alumina typically exhibits hardness around 1800 HV and bulk density near 3.4 g cm‑3. Typical particle size distributions range from 0.1 mm to 1.0 mm for sand grades and 0 - 0.1 mm for micropowder, providing good flow properties and high bulk density. The material’s low porosity and resistance to bursting, pulverising and crazing make it suitable for refractory casting, shaped refractory products and high‑temperature grinding. Standard moisture content is kept below 0.1 percent to maintain performance.
Buyers such as refractory manufacturers, grinding equipment producers and high‑temperature process plants import this abrasive for mould casting, surface finishing and precision grinding. Trade usually involves FOB Luoyang or CIF Shanghai, with packaging in 25 kg bags or bulk drums. The listing does not disclose minimum order quantity, lead time or payment conditions, so importers should request those details directly from the supplier.

Verify the supplier’s corporate registration and request bank references before committing to a purchase. Ask for a sample batch of the fused alumina to evaluate particle size distribution and hardness. Ensure that the stated purity and moisture specifications are documented in a test report.
Discuss incoterms such as FOB Luoyang or CIF Shanghai and obtain a shipping schedule that reflects the typical lead time for furnace‑produced corundum, which is not disclosed in the listing. Confirm that the 25 kg bags are suitable for container loading and that the total weight complies with freight limits. Payment terms are commonly T/T against documents, but buyers should negotiate and obtain a written contract.
Arrange a third‑party inspection to verify hardness, bulk density and moisture content before loading. Request any available quality certificates, such as ISO 9001 or SGS conformity reports. Upon receipt, inspect the bags for damage, confirm the particle size range and retain the inspection report for future reference.
