Ce-TZP vs Mg-PSZ
Ceramic · grade comparison
Ce-TZP and Mg-PSZ are both ceramic grades. Mg-PSZ is the stronger of the two: tensile strength 350 MPa (50.8 ksi) against 330 MPa (47.9 ksi) for Ce-TZP, about 6% more. Mg-PSZ is harder — 1,120 HV against 1,030 HV for Ce-TZP — which matters for wear surfaces and threads. Mg-PSZ is lighter (5.75 g/cm³ vs 6.2 g/cm³ for Ce-TZP) and Mg-PSZ conducts heat better (2.8 W/m·K vs 2.5 W/m·K).
Mg-PSZChoose it when strength drives the design, or when surface hardness matters.
Ce-TZP vs Mg-PSZ: 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.

Ce-TZP vs Mg-PSZ — frequently asked
Is Mg-PSZ stronger than Ce-TZP?
Yes. Mg-PSZ has a typical tensile strength of 350 MPa (50.8 ksi) against 330 MPa (47.9 ksi) for Ce-TZP — about 6% more.
Which is cheaper, Ce-TZP or Mg-PSZ?
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 Ce-TZP over Mg-PSZ?
Pick Mg-PSZ when strength drives the design, or when surface hardness matters.
