Zirconia Ceramic Parts

The tough ceramic for slender loaded and impacted components

The 3 Products in This Family

Zirconia is what you use when the part is slender, carries load or gets handled. At 6.0 g/cm3 with 800 MPa flexural strength and Mohs hardness 8.2, it takes impact far better than alumina, which is why plungers, rods, guides and structural parts are made from it. It is also non-magnetic and corrosion resistant.

Zirconia Ceramic Parts FAQ

When should I choose zirconia over alumina?

Choose zirconia when the part is slender, takes impact or is press fitted. Alumina remains the better choice for thermal and dielectric duty in generous sections.

What is the flexural strength of your zirconia?

800 MPa at a density of 6.0 g/cm3, with Mohs hardness 8.2.

Is zirconia magnetic?

No. Zirconia is non-magnetic, which is one reason it is used near sensors and in instrument equipment.

Can you copy a worn part?

Yes. Send the drawing or the worn sample with the dimensions that have to be held.
