Material for EM-Tec ZC ceramic tweezers tips

Order EM-Tec ZC ceramic tweezers tips

The material used for manufacturing the EM-Tec ZC ceramic tweezers tips is a zirconia toughened alumina (ZTA).

It is used for the following products:
#50-009020 EM-Tec 2A.ZC ceramic replaceable tips tweezers, flat rounded tips
#50-009070 EM-Tec 7.ZC ceramic replaceable tips tweezers, curved fine tips
#50-009071 EM-Tec 71.ZC ceramic replaceable tips tweezers, sharp pointed tips
#50-009072 EM-Tec 72.ZC ceramic replaceable tips tweezers, fine strong tips
#50-009073 EM-Tec 73.ZC ceramic replaceable tips tweezers, pointed strong tips
#50-009074 EM-Tec 74.ZC ceramic replaceable tips tweezers, strong tips


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.
