General remarks:
- Zirconia toughened alumina (ZTA)
- Insulating material
- superior combination of high strength and high hardness
- Very high rigidity, good flexural strength and fracture toughness
- relatively low density
- no open porosity
- very hard surface, excellent wear and abrasion resistance
- excellent thermal properties and high temperature stability
- extreme corrosion resistance; nearly chemically inert
- Typical applications include tweezers for handling samples during thermal, chemical and soldering processes. Handling of hard materials and where very rigid tips are required.
