The main component of brown fused alumina section sand includes: high quality bauxite, anthracite, scrap iron, its fabrication adopts modern new unique technology. It has short grinding time, high efficiency, good economic returns, low price. Brown fused alumina is superior to other abrasives because it has conchoidal fracture, the edge and corner of this conchoidal are sharp. These edges and corners can form new edge and corner in continuous grinding. The most important characteristics of brown fused alumina are high hardness, high-density, stable chemical properties and strong self-sharpening. So, it is the best choice for sand blasting process and grinding and polishing, at the same time, brown fused alumina can be used to sandblasting derusting cleaning artifacts and refractory material.
