Description

With this mixture of ceramics, a small amount of zirconium dioxide is added to the aluminum oxide which significantly improves the hardness and stability and simultaneously increases the toughness. It has following features:


  • Hardness
  • Resistance to pressure
  • Resistance to thermal shock
  • Reistance to temperature
  • Flexural Strenth
  • Los datos sobre este material han sido proporcionados por Bosch Advanced Ceramics.
