PZT vs Y5V
Ceramic · grade comparison
PZT and Y5V are both ceramic grades. PZT is the stronger of the two: tensile strength 75 MPa (10.9 ksi) against 70 MPa (10.2 ksi) for Y5V, about 7% more. Y5V is harder — 570 HV against 350 HV for PZT — which matters for wear surfaces and threads. Y5V is lighter (5.7 g/cm³ vs 7.75 g/cm³ for PZT) and Y5V is stiffer (118 GPa vs 61 GPa).
PZTChoose it when strength drives the design, or when the part sees heat.
Y5VChoose it when surface hardness matters, or when weight is the constraint.
PZT vs Y5V: 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.

PZT vs Y5V — frequently asked
Is PZT stronger than Y5V?
Yes. PZT has a typical tensile strength of 75 MPa (10.9 ksi) against 70 MPa (10.2 ksi) for Y5V — about 7% more.
Which is cheaper, PZT or Y5V?
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 PZT over Y5V?
Pick PZT when strength drives the design, or when the part sees heat. Pick Y5V when surface hardness matters, or when weight is the constraint.
