How Fused Aluminum Oxide Works

  • Fused Aluminum Oxide, also referred to as Fused Alumina, is a synthetic corundum created by reducing fusing high quality alumina powder with different fillers at temperatures under 2000 degrees in an electric arc furnace. Al2O3 dominates its chemical structure, with minor contributions from silicon oxide, ferro oxide, sodium oxide, and water (SiO2).


  • It can be used in the production of abrasive tools, refractory materials, sandblasting, water-jet cutting, steel manufacturing, metallurgical, casting, foundry, and ceramic industries due to its high aluminum oxide concentration, which also gives it a very high refractory temperature.


  • Sandpaper, abrasive tools, sand cloth, and sanding belts are just a few uses for fused aluminum oxide. Sandblasting, polishing, and grinding can be used on both metal and non-metal surfaces. Some of the services provided include water-jet cutting, etching, pattern cutting, wear-proof grinding, abrasion-resistant floor buring, rust removal, cleaning, and polishing of ceramic, wood, metal, and foundry parts. matte-finished copper with a frosted glass appearance.


  • High-quality alumina powder is selected by our qualified specialists, who fuse it in an electric arc furnace before carrying out the customary crushing, shape improvement, sieving, magnetic content removal, and grading into FEPA grits for abrasives and sandblasting. Our aluminum oxide is well self-sharpening, clean, hard, blocky, and has sharp edges.


  • Fused aluminum oxide are created using virtually the same starting ingredients and processing steps. It has a rougher surface than white aluminum oxide and a harder hardness than white corundum. Low-roughness goods like screws, meters, measuring instruments, and blades are acceptable for grinding with it.


  • Pink fused alumina is produced by fusing high grade aluminum oxide with chromium oxide. The amount of chromium oxide employed affects both the color and grain hardness of the finished product. Greater production of chromium oxide additions results in harder grain.
