The M28 m 20 m 14 m 10 m 7 m 5 white corundum is a high‑purity synthetic abrasive produced with an Al₂O₃ content of 99.2 % - 99.6 %. It is supplied in FEPA F grit sizes ranging from M28 down to M5, each conforming to the corresponding mesh specification. The material exhibits a Mohs hardness of 9.0 and a bulk density between 1.75 g/cm³ and 1.95 g/cm³, with a specific gravity of 3.95. The listed chemical composition also includes trace Fe₂O₃ (0.04 % - 0.08 %) and Na₂O (0.23 % - 0.35 %).
In the abrasive market, these grades are standard for both FEPA F and JIS classifications and are typically delivered in 25 kg paper bags or bulk containers for large‑scale users. Typical moisture content is kept below 0.2 % to maintain consistent cutting performance. The abrasive’s particle size distribution follows the FEPA F standard tolerances, ensuring uniform grit and predictable wear rates. While the supplier does not state a specific certification, it is common for manufacturers to provide ISO 9001 quality‑management documentation upon request.
Applications include bonded grinding wheels, coated abrasive discs, sandblasting, refractory linings and precision lapping in ceramic and metalworking industries. Buyers such as abrasive tool manufacturers, furnace builders and surface‑treatment facilities typically order the product in bulk, negotiating terms like FOB Zhengzhou or CIF Shanghai. Importers should confirm the exact packaging size, lead‑time expectations and any required testing certificates directly with Zhengzhou Haixu Abrasives before finalising the contract.
