Product Description

Product Description:

Brown Fused Alumina is produced by fusion of bauxite in an electric arc furnace at high temperatures. The brownish colored product shows high hardness as well as extreme toughness. It is characterized by high temperature resistance, strong erosion resistance, high machinery strength as well as thermal stability, thus making it a great source material for the manufacturing of shaped refractories.


Brown corundum is also environment-friendly due to its low consumption, high recyclability and the fact that it does not contain any hazardous free silicon substances which can lead to silicosis, toxic heavy metals or radioactive pollutants. As brown corundum is very durable and can be reused several times, its low consumption and recyclability result in less waste that needs to be disposed of after use.

All in all, brown corundum brings many advantages to sandblasting surface treatment, such as less dust, high efficiency, low depletion, high quality surface treatment and environmental friendliness, as well as its high recyclability. This explains why brown corundum has become so popular.

1. Ceramic-bonded abrasives: Brown corundum is used in ceramic-bonded abrasives, which are typically used in precision grinding and finishing applications.

2. Resin-bonded abrasives: It is used in resin-bonded abrasives, which are commonly used in manufacturing operations such as cutting, grinding, and polish.

3. Sharpening stones: Brown corundum is used in sharpening stones, mostly used in the kitchen to sharpen knives and other utensils.

4. Cladding welding: It is used in cladding welding to weld metal sheets for various applications, such as architecture and engineering.

5. Thermal spraying: Brown corundum is used as a thermal spraying material for surface coatings.
