High purity: The purity of alumina balls is high, generally can be divided into 99%, 99.5%, 99.7%, 99.9%, 99.99% and other grades, of which 99.99% alumina balls are high-end products.

High hardness: alumina balls have high hardness, generally around 9 Mohs, which is much higher than the hardness of ordinary steel, aluminum, copper and other materials.

High wear resistance: The surface of alumina porcelain balls is smooth and flat, which can effectively reduce wear and extend the service life. At the same time, its wear resistance is also very good, able to withstand the wear and tear of high-speed rotation, high-speed friction and other environments.

High corrosion resistance: The chemical properties of alumina porcelain balls are stable and have good corrosion resistance, suitable for use in strong acids, strong alkalis and other environments.
