Technical Data Sheet: Advanced Ceramic Type “JD”

General Notes:
  • Zirconia Toughened Alumina (ZTA)
  • Superior Combination of High Strength (From Zirconia) and High Hardness (From Alumina)
  • Relatively Low Density
  • No Open Porosity
  • Very Hard Surface, Good Abrasion and Wear Resistance
  • Good Flexural Strength and Fracture Toughness
  • Excellent Thermal Properties and High Temperature Stability
  • Extreme Corrosion Resistance, Nearly Chemically Inert
  • ESD Safe Static Dissipative Material
  • Typical applications include handling of EOS/ESD sensitive components and handling of components during thermal, chemical and soldering processes.  Generally used when very rigid tips are required.
