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.
