Aluminum Nitride vs PZT-5H
Ceramic · grade comparison
Aluminum Nitride and PZT-5H are both ceramic grades. Aluminum Nitride is the stronger of the two: tensile strength 200 MPa (29 ksi) against 75 MPa (10.9 ksi) for PZT-5H, about 167% more. Aluminum Nitride is harder — 1,100 HV against 320 HV for PZT-5H — which matters for wear surfaces and threads. Aluminum Nitride is lighter (3.29 g/cm³ vs 7.5 g/cm³ for PZT-5H) and Aluminum Nitride is stiffer (320 GPa vs 60 GPa).
Aluminum NitrideChoose it when strength drives the design, or when surface hardness matters.
Aluminum Nitride vs PZT-5H: 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.

Aluminum Nitride vs PZT-5H — frequently asked
Is Aluminum Nitride stronger than PZT-5H?
Yes. Aluminum Nitride has a typical tensile strength of 200 MPa (29 ksi) against 75 MPa (10.9 ksi) for PZT-5H — about 167% more.
Which is cheaper, Aluminum Nitride or PZT-5H?
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 Aluminum Nitride over PZT-5H?
Pick Aluminum Nitride when strength drives the design, or when surface hardness matters.
