Product Description

Product Description:

Brown corundum is an artificial product made of high-quality bauxite, anthracite and iron filings. It's created by melting them together at a temperature of 2000°C or higher. Utilizing a self-grinding machine, the crushed and plasticized materials are then magnetically selected to remove the iron filaments, and sieved to create a range of sizes.


The output of this process is dense and hard, and its spherical pellets are perfect for producing ceramic, high-resistance abrasive resin and grinding, polishing, sandblasting, and precision casting. It can also be used for creating high-grade refractories.



Brown corundum abrasive particles boast outstanding properties, such as high strength, durability, cutting rate, thermal shock, and chemical stability.These particles are highly resistant to breaking, meaning they last longer and require fewer replacements, allowing for faster and more efficient cutting, resulting in reduced production time and costs.


Moreover, brown corundum is chemically inert, thereby avoiding contamination of the end-product during processing.In addition, brown corundum is noted for its superb chemical stability, and it can remain intact and unharmed even in the presence of other materials.


Finally, it is worthy of mention that brown corundum has excellent thermal shock resistance, making it an ideal option for applications that involve high temperatures.

Brown corundum is a highly versatile material that has applications in a wide range of industries. It can be used in ceramic-bonded abrasives, which are typically used in precision grinding and finishing applications. It is also used in resin-bonded abrasives, which are commonly used in manufacturing operations such as cutting, grinding, and polish. In addition, brown corundum can be found in sharpening stones, mostly used in the kitchen to sharpen knives and other utensils. It is also used in cladding welding to weld metal sheets for various purposes, such as architecture and engineering purposes.


Furthermore, brown corundum is used as a thermal spraying material for coating surfaces, as well as for glass polishing to remove scratches and stains on the surface of glasses. It is also used in lapping to create extremely smooth surfaces in various high-precision operations and for honing to improve the roundness and straightness of cylinders.
