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.
