PZT-4 vs Y5V

Ceramic · grade comparison

PZT-4 and Y5V are both ceramic grades. PZT-4 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 320 HV for PZT-4 — which matters for wear surfaces and threads. Y5V is lighter (5.7 g/cm³ vs 7.5 g/cm³ for PZT-4) and Y5V is stiffer (118 GPa vs 70 GPa).

PZT-4Choose 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-4 vs Y5V — frequently asked

Is PZT-4 stronger than Y5V?

Yes. PZT-4 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-4 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.

Which is easier to machine, PZT-4 or Y5V?

PZT-4, by a small margin. Both rate not recommended for machinability — 12/100 against 5/100 for Y5V.
