White Aluminium Oxide abrasive is electrically fused in an arc furnace at very high temperatures from bayer processed alumina as raw material. Compared to Brown Aluminium Oxide, the White has a slightly lower abrasive toughness but has a higher hardness and better cutting characteristics.
With a Mohs hardness of 9, Aluminium Oxide is a high strength, wear-resistant material possessing a strong ability to resist chemical attacks (such as acid and alkali) at extreme temperatures. Its high degree of refractoriness, along with its superior electrical insulating properties and high melting point make Aluminium Oxide a desirable material choice for a diverse range of applications.
Common uses and industries include Anti-Slip, Concrete Strengthening, Blasting Media, Grinding, Polishing, Lapping, Metal Preparation, Ceramic Shapes, Laminates, Coatings, Filtration, Abrasives, Polishing, Milling, Filler, Electrical Insulator, Refractories.
Compared to Brown, Fused White Aluminium Oxide has a “higher hardness and better cutting characteristics”
