Product Introduction
High purity aluminum oxide abrasive is an abrasive product mainly made of high-purity alumina. Its chemical formula is AL2O3 and it has high purity, hardness and strength. It features excellent grinding performance and impact resistance, performs well in applications like grinding and polishing, meeting the needs of different fields for high precision and efficiency machining.
Product Advantages
High Purity
High purity aluminum oxide abrasive stands out with its purity level exceeding 99.9%. This high purity translates to extremely low impurity content in the abrasive, directly enhancing efficiency and precision during grinding. The pure alumina particles distribute more evenly on the grinding surface, reducing friction irregularities caused by impurities, thus increasing grinding speed while decreasing scratches and damage to the workpiece surface, resulting in a higher finish quality of the final product.
Excellent Hardness
High purity aluminum oxide abrasive boasts a Mohs hardness close to 9, second only to diamond. This exceptional hardness allows the high-purity alumina abrasive to remain sharp for extended periods during grinding, effectively cutting material and reducing wear, thereby significantly extending the lifespan of grinding tools. Compared to conventional abrasives, its lifespan can be increased by over 30%, lowering long-term costs for users.
Strong Thermal Stability
High purity aluminum oxide abrasive exhibits outstanding thermal stability, capable of enduring temperatures up to 2000°C without undergoing phase changes or decomposition. This characteristic makes it perform exceptionally well in grinding operations under high-temperature conditions, such as metal cutting and pre-treatment before welding. Even in extreme temperatures, the abrasive maintains stable grinding performance, ensuring processing quality and efficiency.
High Corrosion Resistance
High-purity alumina is chemically stable and demonstrates good corrosion resistance to most acids, bases, and organic solvents. This property enables High purity aluminum oxide abrasive to be used in applications involving sensitive materials or corrosive environments, such as semiconductor manufacturing and precision optical component processing. Its corrosion resistance effectively protects workpieces from chemical erosion while extending the lifespan of grinding tools.
