Morgan Advanced Ceramics Sintox ™ FF Mac-A950R-5 Aluminum Oxide Ceramic
Categories: Ceramic; Oxide; Aluminum Oxide

Material Notes: Alumina ceramic with a minimum Al2O3 content of 95.0% (typically 96%). This material is a high quality electrical insulator, with good mechanical properties, that is widely used for components in consumer products as well as for high integrity applications. This grade also has well controlled grain size to enable high integrity molybdenum metallising with our proprietary molybdenum based inks.

Prime Features:

  • High volume resistivity
  • Low coefficient of expansion
  • Dense, non-porous and vacuum tight
  • Resists abrasive wear and chemical attack
  • Fire resistant and non-outgassing
  • Readily accepts molybdenum based metallising for high temperature brazing of assemblies
Typical Applications:
  • Laser power tubes
  • Telecommunications components
  • Aerospace components
  • Automobile components
  • Domestic product components
  • Process equipment components
  • High vacuum equipment and scientific instruments where ceramic components need to be brazed to form high strength connections and complex assemblies
  • Insulators for probes and sensors. Insulators for vacuum pumps
  • Transducer components
  • Gun assemblies and connectors for x-ray optics and electron microscopes
Production Capabilities:
  • Pressed and machined components
  • Extruded components
  • Prototype, batch and volume production
  • High temperature brazing of assemblies
  • Metallising of components
