PZT vs PZT-2

Ceramic · grade comparison

PZT and PZT-2 are both ceramic grades. PZT is harder — 350 HV against 320 HV for PZT-2 — which matters for wear surfaces and threads. PZT-2 is stiffer (86 GPa vs 61 GPa).

PZTChoose it when surface hardness matters.

PZT vs PZT-2 — frequently asked

What is the difference between PZT and PZT-2?

PZT and PZT-2 are both ceramic grades. PZT is harder — 350 HV against 320 HV for PZT-2 — which matters for wear surfaces and threads. PZT-2 is stiffer (86 GPa vs 61 GPa).

Which is cheaper, PZT or PZT-2?

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 PZT-2?

Pick PZT when surface hardness matters.
