Morgan Advanced Ceramics Deranox™ 975 Alumina


Subcategory: Oxide, Aluminum; Oxide

Key Words: Al2O3; Aluminum Oxide

Material Notes:
Fine grain alumina ceramic of 97.5% Al2O3 content. A high quality material, widely used for electrical and mechanical components that require thick film metallizing, as well as for dynamic duties where resistance to abrasion and chemical attack are essential.

Prime features:

  • Can be thick film metallized with noble metals
  • High volume resistivity
  • High mechanical strength
  • Excellent corrosion resistance
  • Excellent wear resistance
  • Low coefficient of friction
  • High thermal stability
  • High density, non-porous and vacuum tight
