Henan Hongtai main China manufacturer for white fused alumina refractory
Henan Hongtai is one of the China main white fused alumina refractory manufacturer located in Xinmi, Henan. White fused alumina is made from industrial alumina powder, smelted at a high temperature of more than 2250 degrees in an electric arc, and then cooled. It is crushed and shaped, iron is removed by magnetic separation, and sieved into a variety of particle sizes. White fused alumina has a dense texture, high hardness and sharp corners.
White fused alumina is suitable for manufacturing ceramics, resin-bonded abrasive tools, grinding, polishing, sandblasting, precision casting (corundum for precision casting), etc. It can also be used for manufacturing high-grade refractory materials. The code "WA" is consistent with international general standards and national standards.
White fused alumina is a kind of artificial abrasive, the content of aluminum oxide (Al2O3) is more than 99%, and contains a small amount of iron oxide, silicon oxide and other components, which is white.
White fused alumina particle size is produced according to international standards and national standards, and can be processed according to user requirements. The general particle size is F4~F220, and its chemical composition varies depending on the particle size. The outstanding feature is that the crystal size is small and impact resistant. If white fused alumina is processed and broken by a self-mill, the particles are mostly spherical particles, and the surface is dry and clean, and it is easy to bond with the binder.

White Fused Alumina has higher hardness and slight lower toughness comparing with brown fused alumina. White fused alumina is also characterized by its high purity, ability of self-sharpening, better cutting, less heat emits, higher efficiency, acid and alkali resistance, good thermal stability. As abrasive material, White Fused Alumina is widely used for bonded and coated abrasive, polishing, precision casting and so on.
