Product Description

Product Description:

Brown corundum is produced using high-quality bauxite, anthracite, and iron filings. The material is subjected to arc smelting at a temperature of 2000°C or higher. Subsequently, it is crushed and plasticized using a self-grinding machine, magnetically sorted to remove iron particles, and graded into various sizes. The texture of brown corundum is incredibly dense and hard and comes in high spherical pellets.


Brown corundum abrasives have highly desirable characteristics, including high purity, good crystallization, strong fluidity, low coefficient of linear expansion, and corrosion resistance. Over the years, this abrasive has been utilized by various fire-proof production companies, who have verified that it does not crack, chalk, or explode during use. This product has proven to be even more cost-effective than traditional brown corundum abrasives and is the ideal filler for fused alumina refractories.


Additionally, brown corundum is well-suited for fabricating ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, and high-grade refractories.



Less Dust

Brown corundum is used as a sandblasting surface treatment due to its relatively high density, which produces less dust during the process of sandblasting. This ensures the health and safety of the operator while improving their visibility. In comparison to slag and quartz sand, brown corundum is less brittle and has a smaller particle size, reducing the amount of environmental pollution created.


High Efficiency

Under a certain pressure, brown corundum quickly impacts the surface of an object with a large number of sharp edges. This makes it a very fast spray grinding method, with a higher cleaning rate than other conventional abrasives.


Low Depletion

The unique particle size of brown corundum ensures that more effective particles can hit the surface of the object, greatly reducing the loss of abrasive during use.



Brown corundum can be reused several times before losing its cutting ability and can be recycled for use in the construction industry as a cement additive.


Technical Parameters:

Chemical Constitution:

The chemical constitution of the material is as follows:

  • Al2O3 ≥96.3%
  • SiO2 ≤1.4%
  • Fe2O3 ≤0.21%
  • TiO2 ≤1.5%


Physical Properties:

The physical properties of the material are as follows:

  • Color: Dark Brown

Sandblasting is a popular method used in various industries, including environmental protection materials, aluminum profile, copper profile glass, washed jeans, precision molds, and other fields. It involves firing abrasive materials at high speeds to remove surface contaminants, rust, and other substances.


The grinding technique is commonly applied to picture tubes, optical glass, monocrystalline silicon, lenses, watch glass, crystal glass, jade, and other similar materials to produce a smooth and polished surface.


Resin abrasives are another type of abrasive material characterized by having suitable color, good hardness, toughness, suitable particle cross-section type, and edge retention.
