Technical Data Sheet: Advanced Ceramic Type “KD”®

General Notes:

  • Zirconia Toughened Alumina (ZTA)
  • A 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.
