C0G/NP0 vs PLZT
Ceramic · grade comparison
C0G/NP0 and PLZT are both ceramic grades. C0G/NP0 is the stronger of the two: tensile strength 60 MPa (8.7 ksi) against 40 MPa (5.8 ksi) for PLZT, about 50% more. C0G/NP0 is harder — 680 HV against 380 HV for PLZT — which matters for wear surfaces and threads. C0G/NP0 is lighter (5.7 g/cm³ vs 7.85 g/cm³ for PLZT) and C0G/NP0 is stiffer (120 GPa vs 68 GPa).
C0G/NP0Choose it when strength drives the design, or when surface hardness matters.
C0G/NP0 vs PLZT: 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.

C0G/NP0 vs PLZT — frequently asked
Is C0G/NP0 stronger than PLZT?
Yes. C0G/NP0 has a typical tensile strength of 60 MPa (8.7 ksi) against 40 MPa (5.8 ksi) for PLZT — about 50% more.
Which is cheaper, C0G/NP0 or PLZT?
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 C0G/NP0 over PLZT?
Pick C0G/NP0 when strength drives the design, or when surface hardness matters.
