Product Description

Product Description:

Industrial Grade Colour Of Aluminium Oxide With Stable Density

Brown corundum is made of high-quality bauxite as raw material, anthracite and iron filings. It is made by arc smelting at 2000°C or higher temperature. It is crushed and plasticized by self-grinding machine, magnetically selected to remove iron, sieved into various sizes, and its texture is dense and hard.High, spherical pellets, suitable for the production of ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, precision casting, etc., can also be used to manufacture high-grade refractories.

 

The brown corundum abrasive has the characteristics of high purity, good crystallization, strong fluidity, low coefficient of linear expansion, and corrosion resistance. The practice of dozens of fire-proof production companies has verified that this product has the characteristics of no explosion, no chalking, and no cracking in the application process. In particular, it is much higher than the cost-effectiveness of traditional brown corundum, making it the best aggregate and filler for fused alumina refractories.

 

Features:

The Advantages of using Brown Corundum for Sandblasting

Brown corundum is a common material for surface treatment and grinding because of it's relatively high density. This provides several advantages over other sandblasting materials.

  • Less dust, ensuring operator health and safety, and better visibility.

  • High efficiency due to the sharp edges of brown corundum quickly impacting the surface of the object.

  • Low depletion since the unique particle size of brown corundum ensures more effective particles hitting the surface of the object.

  • High quality surface treatment since brown corundum can penetrate deep into the holes and pits, and reach the bare surface of the metal.

  • An environmentally friendly material because brown corundum is non-toxic, and doesn't contain harmful free silicon substances, toxic heavy metals or radioactive pollutants.

  • Recyclable, since it can be reused several times without losing its cutting ability.

 

Technical Parameters:

The chemical constitution of Al2O3 is composed of 96.3%, SiO2 at 1.4%, Fe2O3 at 0.21%, and TiO2 at 1.5%.

In terms of physical properties, the appearance of Al2O3 is brown. The Mohs hardness is 9. It has a true density of 3.9 g/cm3, and a bulk density of 1.60~1.95g/cm3. The Ig-Loss is 0.09%.

 

Applications:

Brown corundum is widely used in a variety of industrial applications due to its excellent properties. It is used as an abrasive in wire sawing operations for cutting complex shapes in a wide range of materials. It is also used in precision casting processes, as lining materials for furnaces and kilns, and as a binding agent in diamond grinding wheels. In addition, brown corundum is used in grinding pastes, ultrasonic grinding, metal surface treatments, dry sanding, producing cutting discs, and as a coated abrasive in sandpaper and abrasive belts. Finally, it is used as a non-skid flooring material in high traffic areas.
