CeramaZirc 3YZ
CeramaZirc Nano HIP
Dubbed ‘ceramic steel’ Zirconia (ZrO2) ceramic materials offers a combination of high hardness, wear and corrosion resistance while still maintaining one of the highest figures for fracture toughness amongst ceramic materials.
Under the tradename CeramaZirc, Precision Ceramics offers a new range of Zirconia materials spanning from conventional sintered Zirconia to high performance Nano Zirconia consolidated by Hot Isostatic Pressing and all now manufactured ‘in-house’ in a brand new facility at our UK headquarters in Birmingham.
- Use temperatures up to 1000°C
- Low thermal conductivity
- Chemical inertness
- Resistance to molten metals
- Wear resistance
- High fracture toughness
- High hardness
