Zirconia Ceramic Parts
Unlike other ceramic materials, zirconia is a material with very high resistance to crack propagation. And its fine grain size enables excellent surface finishes and the ability to hold a sharp edge. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel.
Components made from this material are more expensive than components made of alumina ceramics. Zirconium oxide ceramics are used among other applications, as tools for wire forming, as auxiliaries in welding processes, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.
Magnesia-partially-stabilised zirconia (MgO-PSZ) and yttria-partially stabilised zirconia (Y-TZP) in particular offer an outstanding resistance to mechanical shocks as well as to flexural load, because of their high fracture toughness and relative “ elasticity ”. These two zirconias are advanced ceramics of choice for severe mechanical applications.
Properties
MgO-PSZ and Y-TZP zirconias have the following features :

Tigar's zirconia ceramics are harder than steel and chrome alloys and, since they do not have a binder phase, are much more corrosion resistant than tungsten carbide (WC). Our zirconias have a pristine structure, which allows them to be polished to a mirror finish. This finish, the extremely low coefficient of friction, and the hardness mitigates pick up or galling encountered in can tooling and extends the overall life.
Zirconia is approximately 2.5 times lighter than tungsten carbide so zirconia parts will put less stress and increase the life of the mating bearings and shafts in can making equipment.
