PbNb2O6 vs PZT-4
Ceramic · grade comparison
PbNb2O6 and PZT-4 are both ceramic grades. PZT-4 is the stronger of the two: tensile strength 75 MPa (10.9 ksi) against 25 MPa (3.63 ksi) for PbNb2O6, about 3.0 times as much. PZT-4 is the more ductile: elongation 0.1% versus 0.05% for PbNb2O6, and PZT-4 is harder (320 HV vs 300 HV). PbNb2O6 is lighter (5.9 g/cm³ vs 7.5 g/cm³ for PZT-4) and PZT-4 is stiffer (70 GPa vs 45 GPa).
PbNb2O6Choose it when weight is the constraint, or when the part sees heat.
PZT-4Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
PbNb2O6 vs PZT-4: 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.

PbNb2O6 vs PZT-4 — frequently asked
Is PZT-4 stronger than PbNb2O6?
Yes. PZT-4 has a typical tensile strength of 75 MPa (10.9 ksi) against 25 MPa (3.63 ksi) for PbNb2O6 — about 3.0 times as much.
Which is cheaper, PbNb2O6 or PZT-4?
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.
Which is easier to machine, PbNb2O6 or PZT-4?
PZT-4, by a small margin. Both rate not recommended for machinability — 12/100 against 6/100 for PbNb2O6.
