OEM/ODM:The normal Lead time is 15-45 days, which     depends on your quantiy.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.  Feature1. High Temperature Up to 1800ºC2. High Voltage Resistance3. High Mechanical Strength and Hardness4. Excellent Insulation Performance5. High Corrosion Resistance6. Extremly Abrasion Resistance Performance7.
