White fused alumina powder, also known as emery or corundum, is a synthetic aluminum oxide abrasive produced from Bayer‑process alumina. The material contains at least 99.0 % Al₂O₃, shows a Mohs hardness of 9.0 + and is supplied in grain sizes ranging from F8 to F1200. It is characterised by high purity, self‑sharpening behaviour and low frictional heat during grinding. The product is exported in 25 kg bags or jumbo sacks from Zhengzhou, Henan, China.
The powder is available in chemically washed and non‑washed forms, as well as in normal and high bulk‑density grades. Typical industry practice lists bulk density between 1.75 and 1.95 g cm⁻³ and true density between 3.95 and 3.97 g cm⁻³. Standard FEPA classifications from F8 to F1200 are used worldwide, and the material is often supplied with a certified analysis report. The supplier’s laboratory is accredited by a government inspection bureau, ensuring consistency across batches.
Typical users include manufacturers of high‑speed steel, chilled steel and other high‑carbon alloys that require precise grinding or lapping. The abrasive is also employed as a polishing medium, catalyst carrier, and in refractory ceramics. Buyers usually request bulk shipments and confirm certifications such as GB, ISO, FEPA and JIS before placing orders. Pricing, minimum order quantity and lead‑time are provided on request, and the supplier can arrange FOB or CIF terms according to the buyer’s preference.
