Pump Seal 1800HV Alumina Ceramic Disc 3.9g/Cm3

Advanced High Purity Alumina Ceramic Round Disc


Description:


Aluminium Oxide 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.
