99.7% Alumina Ceramic Grinding Disc
High-Precision Grinding Solution
A ceramic grinding ceramic disc with 99.7% alumina content is a high-performance precision grinding tool. Its main component is high-purity α-alumina, with a density typically ≥3.89 g/cm³ and a Rockwell hardness of HRA85 or above. This material exhibits an extremely low wear rate, uniform structure, and high chemical stability, showing almost no reaction with common acids, alkalis, and solvents, thereby preventing contamination during the grinding process.
