Brown fused aluminum oxide is an artificial corundum material made from bauxite as the main raw material through high-temperature electric furnace smelting. It possesses characteristics such as high hardness, high toughness, high temperature resistance, and corrosion resistance, and is widely used in abrasives, refractories, sandblasting, and other fields.
brown fused aluminum oxide Application Scenarios
Specific uses of brown fused alumina as an abrasive:
1. Sandblasting brown fused alumina (widely used in aluminum profiles, copper profiles, glass, washed denim, precision molds, etc.);
2. Free grinding (applied in cathode ray tubes, optical glass, single-crystal silicon, lenses, watch glass, crystal glass, jade, etc.);
3. Resin bonded abrasives (due to its suitable color, good hardness, toughness, appropriate particle cross-section type and edge retention, it is ideally suited for use in resin bonded abrasives).
II. Brown Fused Alumina Refractory Materials:
Brown fused alumina has been widely used in refractory materials in recent years, such as iron ladle castables, anhydrous ramming mixes, corundum bricks, precast shapes, permeable bricks, ladle bricks, and magnesia-alumina-carbon bricks.
brown fused aluminum oxide Advantages
01. Brown fused alumina has moderate hardness.
It has high hardness, good toughness, and a long service life.
02. Finely screened, free of impurities, and not easily broken.
It is not easily broken under repeated high-speed impacts, resulting in a longer service life and lower cost.
03. Fast cleaning speed improves efficiency.
Even and rapid cleaning shortens surface treatment time and improves work efficiency.

brown fused aluminum oxide characteristics
1. Because of its high temperature resistance, corrosion resistance, high strength and other properties, it is used for pouring steel sliding spout, smelting rare metals, special alloys, ceramics, iron-making blast furnace lining (wall and tube), physical and chemical vessels, spark plugs, heat-resistant and anti-oxidation coatings.
2. Due to the characteristics of high hardness, good wear resistance and high strength. In the chemical system, it is used to make various reaction vessels and pipes, parts of chemical pumps; to make mechanical parts, various molds, such as wire drawing die, extruded pencil core die mouth, etc.; to make knives, mold abrasives, bulletproof materials, human joints, sealing die rings, etc.
3. Corundum insulation materials, such as corundum lightweight bricks, corundum hollow spheres and fiber products, are widely used in the walls and roofs of various high-temperature furnaces, both high-temperature resistant and heat preservation.
