Brown fused alumina is a man-made abrasive, the main component of which is aluminum oxide (Al2O3), which is made by melting bauxite, carbon materials and iron filings at high temperature in an electric arc furnace. Due to its high hardness and good toughness, it is widely used in grinding, polishing and other fields.
MOQ:
customUsed to manufacture advanced refractory materials, castables, refractory bricks, etc.
1、Sandblasting-the abrasive has moderate hardness, high bulk density, no free silica, high specific gravity, and good toughness. It is an ideal “environmentally friendly” sandblasting material. It is widely used in aluminum profiles, copper profiles, glass, and washed jeans. Precision molds and other fields;
2、Free grinding-grinding grade abrasive, applied to free grinding in the fields of picture tube, optical glass, single crystal silicon, lens, watch glass, crystal glass, jade, etc. It is a high-grade grinding material commonly used in China;
3、Resin Abrasives-Abrasives with suitable color, good hardness, toughness, suitable particle cross-section type and edge retention, applied to resin abrasives, the effect is ideal;
4、Coated abrasives-abrasives are raw materials for manufacturers such as sandpaper and gauze;
5、Functional fillers-mainly used for automotive brake parts, special tires, special construction products and other collars, which can be used as wear-resistant materials such as highway roads, airstrips, docks, parking lots, industrial floors, and sports venues;
