Brown fused alumina for brake pad sand blasting/polishing
Description:
Brown fused alumina is produced by melting high-quality bauxite, iron filings, and anthracite in an electric arc furnace at high temperatures 2200℃. The material is then crushed, shaped in a self-grinding machine, iron is removed by magnetic separation, and it is screened into various sizes. The main chemical component is Al2O3, with a content of 94%-96%, along with small amounts of Fe, Si, and Ti. It has a dense texture, high hardness, and is brown in color with great toughness.It is suitable for manufacturing ceramic and resin high-bond abrasives, as well as for grinding, polishing, sandblasting, precision casting, and refractory materials.
