Product Description
AL2O3 Mill Burnisher Parts Coffee Maker Alumina Ceramic Coffee Burr Core
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. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution. | Unit | 95% AL2O3 | 99%AL2O3 | ZrO2 | GP-Si3N4 |
