Brown corundum is a high-quality material made out of bauxite, anthracite, and iron filings. It's produced through arc smelting at a temperature of 2000°C or higher. Brown corundum is later crushed and plasticized using a self-grinding machine and is then magnetically selected in order to remove iron. It's also sieved into various sizes. This material has a dense and hard texture.
These high quality brown corundum pellets are suitable for various purposes such as production of ceramic, high-resistance abrasive resin, grinding, polishing, sandblasting, and precision casting. Moreover, it can also be used to manufacture high-grade refractories.
Brown corundum abrasive particles have many superior qualities. High strength and durability make them highly resistant to breaking, resulting in fewer replacements and extended wear life. Furthermore, these particles perform fast and efficient cutting, resulting in reduced production time and costs.
In addition, the particles are chemically inert, and so do not contaminate the end-product during processing. Their high chemical stability also means that they do not react with other materials. Finally, these abrasive particles have excellent thermal shock resistance, making them suitable for use in high-temperature applications.
