Product Description

Product Description:

Brown corundum is an abrasive that has numerous industrial uses. It is made from high-quality bauxite, anthracite and iron filings through a process of arc smelting at temperatures of 2000°C or higher. After undergoing crushing and plasticizing from a self-grinding machine, the brown corundum goes through a magnetic selection process to remove iron and is then sieved into various sizes. The texture of the final product is dense and hard, forming spherical pellets suitable for production of ceramics, high-resistance abrasives, resin grinding and polishing, sandblasting and precision casting.


With its high purity, good crystallization, low coefficient of linear expansion and excellent corrosion resistance,brown corundum performs admirably in all its different applications. In fact, years of practice by various fire-proof production companies have revealed that brown corundum has excellent durability with no chalking, no explosion and no cracking occurring while in use. Its cost-effectiveness is much higher than traditional brown corundum, making it the ideal aggregate and filler for fused alumina refractories.



Brown Corundum is nowadays widely used for sandblasting surface treatment due to its high density, which results in less dust dispersal during the process. This, in turn, enables a higher degree of operator visibility and safety. Additionally, it is a very efficient method, as its sharp-edged particles under pressure can quickly and effectively work on the surface of the object being treated.


As well as this, the unique particle size of brown corundum ensures that more effective particles are used, greatly reducing the need for additional abrasives. The end result of the process is a high-quality surface treatment, with deep penetration into holes and pits, completely removing rust, water-soluble salts and other pollutants.


Brown corundum is an environmentally friendly choice as it is a non-toxic pure mineral, with no free silicon substances, toxic heavy metals, or radioactive pollutants. Furthermore, it's recyclable, as it can be reused up to several times before needing to be re-purchased.


Technical Parameters:

The chemical constitution of this product includes Al2O3 of 96.3% or more, SiO2 of 1.4% or less, Fe2O3 of 0.21% or less and TiO2 of 1.5% or less.

Concerning its physical properties, the color of this product is brown. It has a Mohs hardness of 9, a true density of 3.9 g/cm3 and a bulk density of 1.60~1.95g/cm3. Additionally, the Ig-Loss is 0.09% or less.



Brown corundum is a versatile material with a range of applications across many industries. It is used in wire sawing operations for cutting complex shapes in a wide range of materials. It is also used in precision casting, which produces high accuracy components for the aerospace, automotive and medical industries.


Brown corundum is highly heat resistant and is used in lining materials for furnaces and kilns. It is also used in grinding pastes for various applications such as optical lens grinding, tool manufacturing and polishing. In addition, brown corundum is used in ultrasonic grinding, a non-contact machining process used in surface finishing and material removal operations.


Brown corundum is also used as a binding agent in diamond grinding wheels, typically used in high-precision grinding operations. It is also used in metal surface treatment, including cleaning, degreasing and polishing. It is used to make cutting discs for cutting stone and concrete, in dry sanding for removing stains and cleaning surfaces on metals and other materials, and to produce coated abrasive products such as sandpaper and abrasive belts.


Finally, brown corundum can be used as a non-skid flooring material, providing traction and preventing slips and falls in high traffic areas.
