3Y-TZP Zirconia vs Mg-PSZ
Ceramic · grade comparison
3Y-TZP Zirconia and Mg-PSZ are both ceramic grades. 3Y-TZP Zirconia is harder — 1,250 HV against 1,120 HV for Mg-PSZ — which matters for wear surfaces and threads. Mg-PSZ is lighter (5.75 g/cm³ vs 6.05 g/cm³ for 3Y-TZP Zirconia) and Mg-PSZ conducts heat better (2.8 W/m·K vs 2.5 W/m·K).
3Y-TZP ZirconiaChoose it when surface hardness matters.
Mg-PSZChoose it when weight is the constraint.
3Y-TZP Zirconia 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.

3Y-TZP Zirconia vs Mg-PSZ — frequently asked
What is the difference between 3Y-TZP Zirconia and Mg-PSZ?
3Y-TZP Zirconia and Mg-PSZ are both ceramic grades. 3Y-TZP Zirconia is harder — 1,250 HV against 1,120 HV for Mg-PSZ — which matters for wear surfaces and threads. Mg-PSZ is lighter (5.75 g/cm³ vs 6.05 g/cm³ for 3Y-TZP Zirconia) and Mg-PSZ conducts heat better (2.8 W/m·K vs 2.5 W/m·K).
Which is cheaper, 3Y-TZP Zirconia 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 3Y-TZP Zirconia over Mg-PSZ?
Pick 3Y-TZP Zirconia when surface hardness matters. Pick Mg-PSZ when weight is the constraint.
