8Y-FSZ vs Ce-TZP
Ceramic · grade comparison
8Y-FSZ and Ce-TZP are both ceramic grades. Ce-TZP is the stronger of the two: tensile strength 330 MPa (47.9 ksi) against 150 MPa (21.8 ksi) for 8Y-FSZ, about 120% more. 8Y-FSZ is harder — 1,300 HV against 1,030 HV for Ce-TZP — which matters for wear surfaces and threads. 8Y-FSZ is lighter (5.95 g/cm³ vs 6.2 g/cm³ for Ce-TZP) and 8Y-FSZ runs hotter in service (1,500°C vs 1,000°C continuous).
8Y-FSZChoose it when surface hardness matters, or when weight is the constraint.
Ce-TZPChoose it when strength drives the design.
8Y-FSZ vs Ce-TZP: 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.

8Y-FSZ vs Ce-TZP — frequently asked
Is Ce-TZP stronger than 8Y-FSZ?
Yes. Ce-TZP has a typical tensile strength of 330 MPa (47.9 ksi) against 150 MPa (21.8 ksi) for 8Y-FSZ — about 120% more.
Which is cheaper, 8Y-FSZ or Ce-TZP?
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 8Y-FSZ over Ce-TZP?
Pick 8Y-FSZ when surface hardness matters, or when weight is the constraint. Pick Ce-TZP when strength drives the design.
