Product Description
 | Alumina Ceramic Aluminium Oxide, Al2O3 is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. |
Alumina Ceramic ring 95% alumina ceramic seal ring (Al₂O₃ ≥95%) is a key wear‑resistant sealing component for magnetic pumps. Manufactured by dry‑press forming, high‑temperature sintering and precision grinding. The sealing face is finely lapped for zero‑leakage operation of magnetic drive pumps. It is a good replacement for metal and graphite sealing parts, widely used in chemical anti‑corrosion magnetic pumps. |  |
 | Alunina Ceramic Parts Features The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution. |
Alumina Ceramics We can make the part by hot injection pressing, dry pressing, 200T isostatic pressing and extrusion productive technology etc. |  |
