3Y-TZP Zirconia vs 8Y-FSZ
Ceramic · grade comparison
3Y-TZP Zirconia and 8Y-FSZ are both ceramic grades. 3Y-TZP Zirconia is the stronger of the two: tensile strength 350 MPa (50.8 ksi) against 150 MPa (21.8 ksi) for 8Y-FSZ, about 133% more. 8Y-FSZ runs hotter in service (1,500°C vs 1,000°C continuous) and 3Y-TZP Zirconia conducts heat better (2.5 W/m·K vs 2.2 W/m·K).
3Y-TZP ZirconiaChoose it when strength drives the design.
8Y-FSZChoose it when the part sees heat.
3Y-TZP Zirconia vs 8Y-FSZ: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all ceramic grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

3Y-TZP Zirconia vs 8Y-FSZ — frequently asked
Is 3Y-TZP Zirconia stronger than 8Y-FSZ?
Yes. 3Y-TZP Zirconia has a typical tensile strength of 350 MPa (50.8 ksi) against 150 MPa (21.8 ksi) for 8Y-FSZ — about 133% more.
Which is cheaper, 3Y-TZP Zirconia or 8Y-FSZ?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
When should I choose 3Y-TZP Zirconia over 8Y-FSZ?
Pick 3Y-TZP Zirconia when strength drives the design. Pick 8Y-FSZ when the part sees heat.
