Order EM-Tec ZE ESD safe ceramic tweezers tips
The material used for manufacturing the EM-Tec ZE ESD safe ceramic tweezers tips is a doped zirconia toughened alumina (ZTA)
It is used for the following products:
#50-008020 EM-Tec 2A.ZE ESD safe ceramic replaceable tips tweezers, flat rounded tips
#50-008071 EM-Tec 71.ZE ESD safe ceramic replaceable tips tweezers, sharp pointed tips
#50-008072 EM-Tec 72.ZE ESD safe ceramic replaceable tips tweezers, pointed strong tips
General remarks:
- Zirconia toughened alumina (ZTA)
- ESD safe static dissipative 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 handling of ESD sensitive components, handling of sample during thermal, chemical and soldering processes. Handling of hard materials and where very rigid tips are required.
