Al2O3 Mill Burnisher Parts Coffee Maker Alumina Ceramic Coffee Burr Core

AL2O3 Mill Burnisher Parts Coffee Maker Alumina Ceramic Coffee Burr CoreAluminium 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.Unit95% AL2O399%AL2O3ZrO2GP-Si3N4Densityg/cm³3.653.885.953.22Color-WhiteIvoryWhiteGrayWater Absorption%0000Young's ModulusGpa280350205295Vickers HardnessGpa14201218-20Flexural Strength ( at R.T. )Mpa280300900650Compressive Strength ( at R.T. )Mpa2000250022002200Thermal Conductivity ( at R.T. )W/(m.K)18-25302225Thermal Shock Resistance△t (ºC )220180-200280-350450-650Max Working Temperature ( at R.T.)ºC150017008501200Volume Resistivity ( at R.T. )Ω.cm>10^15>10^14>10^12>10^14Dielectric Constant ( 1MHz at R..T.)-9.509.80268.20Dielectric StrengthkV/mm1622-16* Features:
