ATZ vs Ce-TZP
Ceramic · grade comparison
ATZ and Ce-TZP are both ceramic grades. ATZ is the stronger of the two: tensile strength 400 MPa (58 ksi) against 330 MPa (47.9 ksi) for Ce-TZP, about 21% more. ATZ is harder — 1,400 HV against 1,030 HV for Ce-TZP — which matters for wear surfaces and threads. ATZ is lighter (5.5 g/cm³ vs 6.2 g/cm³ for Ce-TZP) and ATZ is stiffer (240 GPa vs 205 GPa).
ATZChoose it when strength drives the design, or when surface hardness matters.
ATZ 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.

ATZ vs Ce-TZP — frequently asked
Is ATZ stronger than Ce-TZP?
Yes. ATZ has a typical tensile strength of 400 MPa (58 ksi) against 330 MPa (47.9 ksi) for Ce-TZP — about 21% more.
Which is cheaper, ATZ 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 ATZ over Ce-TZP?
Pick ATZ when strength drives the design, or when surface hardness matters.
