Aluminiumoxid Wärmeleitscheiben

Aluminium Oxide (Al 2O 3)

Aluminium oxide (Al 2O 3) with its different levels of purity, is the most used ceramic high-tech material.


  • High electric insulation (1x1014 to 1x1015 Ωcm)
  • Between medium and extreme high mechanical strength (300 to 630 MPa)
  • Very high strength against pressure (2000 to 4000 MPa)
  • High hardness (15 to 19 GPa)
  • Medium heat conductivity (20 to 30 W/mK)
  • High resistance against corrosion and erosion
  • Excellent slide characteristic
  • Low mass density (3,75 to 3,95 g/cm³)
  • Operating temperature without mechanical stress
  • Bio inert and food compatibility
