Morgan Advanced Ceramics Deranox™ 970 Mac-A970R Aluminum Oxide Ceramic
Categories: Ceramic; Oxide; Aluminum Oxide

Material Notes: High-quality alumina ceramic of 97.0% Al2O3 content. This material is an excellent electrical insulator that can be metallized to facilitate high-temperature brazing of assemblies.

Prime Features:

  • Readily accepts metallizing with moly-manganese
  • Very high volume resistivity
  • Low loss, constant high dielectric
  • High density, non-porous and vacuum tight
  • Resists abrasive wear and chemical attack
Typical Applications: Metallized ceramic components used in high-integrity applications, including:
  • High-vacuum systems
  • Laser equipment (gas, solid-state and waveguide)
  • X-ray tubes and electron microscopes
  • Microwave windows
  • Insulators in medical and scientific equipment
Production Capabilities:
  • Complex pressed and machined components
  • Grinding, lapping polishing to precise limits
  • Moly-manganese metallizing
  • Brazed assemblies
