Technical Data Sheet: Advanced Ceramic Type “JD”

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.
