White fused alumina fine powder 200-0/325
It exhibits excellent chemical stability and boasts outstanding insulating properties. It is particularly well-suited for grinding and polishing precision components, as well as for manufacturing high-grade refractory materials. Moreover, due to the unique characteristics of white fused alumina fine powder itself, it has increasingly become the preferred abrasive material in a growing number of high-end industries.
It has an extremely low coefficient of thermal expansion, excellent hydrophilicity, exceptional toughness, and high strength. Sintered abrasive tools made from this material exhibit a deep blue color after firing, show no network cracks, and remain free of rust stains. As a result, these tools offer enhanced precision and superior grinding performance, making them particularly well-suited for the production of high-grade bonded abrasive tools.

Refractory material brown corundum
Brown corundum boasts high purity, excellent crystallinity, strong fluidity, a low linear expansion coefficient, and excellent corrosion resistance. Verified through practical application by dozens of refractory material manufacturers, this product exhibits characteristics such as no spalling, no pulverization, and no cracking during use. In particular, its cost-effectiveness—far superior to that of conventional brown corundum—makes it an ideal aggregate and filler for brown-corundum-based refractory materials.
