Product Description

Product Description:


Brown corundum is made from high-quality bauxite, anthracite, and iron filings. It is produced through arc smelting at a temperature of 2000°C or higher. The mixture is crushed and kneaded in a self-grinding machine, and then iron is removed using a magnet. Finally, it is sieved into different sizes and its texture becomes dense and hard.


Brown corundum is often used to produce ceramic, high-resistance abrasive resin, and it is used for grinding, polishing, sandblasting, and precision casting. It can also be used in the production of high-grade refractories. The pellets have a high degree of sphericity, which makes them suitable for various applications.




Brown corundum abrasive particles are known for their high strength and durability. The particles are highly resistant to breaking, which results in reduced replacement costs since they can be used longer.


In addition, brown corundum abrasive particles offer an incredibly fast and efficient cutting process. This significantly reduces production time and costs.


Moreover, brown corundum abrasive particles are chemically inert, so they won't contaminate the end-product during processing.

Furthermore, they have an excellent chemical stability and thermal shock resistance. Brown corundum abrasive grains won't react with other materials and are capable of withstanding sudden temperature changes, making them great for high-temperature applications.

Brown corundum is a versatile material that has numerous uses, from precision grinding and finishing applications to creating extremely smooth surfaces for high-precision operations.It is used in ceramic-bonded abrasives, which are typically used in precision grinding and finishing applications, and in resin-bonded abrasives, which are commonly used in manufacturing operations such as cutting, grinding, and polishing.


Additionally, Sharpening stones, which are mostly used in the kitchen to sharpen knives and other utensils, feature brown corundum.

Considering other applications, brown corundum is used in cladding welding to weld metal sheets for various applications, such as architecture and engineering. It is also used as a thermal spraying material for surface coatings.


Furthermore, it is used in glass polishing to remove scratches and stains on the surface of glasses, and for lapping to create extremely smooth surfaces in various high-precision operations, such as optics, electronics, and aerospace.


Finally, honing, which is required to improve the roundness and straightness of cylinder, uses brown corundum.
