There are many types of piezoelectric materials, each with different properties. Because PZT 5H is a commonly used piezoelectric material, we have written a specific article to introduce PZT-5H.
- What is PZT-5H
- PZT-5H vs PZT-5A
- Characteristics of PZT-5H
- Application of PZT-5H
- The application case of He-shuai company PZT-5H
1、What is PZT-5H
PZT 5H is a type of lead zirconate titanate (PZT) piezoelectric ceramic material. PZT 5H is a modified version of PZT 5A and is a commonly used PZT material. PZT 5H has a Curie temperature (the temperature at which the material’s piezoelectric properties disappear) higher than PZT 5A, making it suitable for high-temperature applications.
PZT 5H has a high piezoelectric charge constant, making it suitable for applications that require high sensitivity. It also has a high mechanical quality factor, which means it can vibrate at low energy loss at high frequencies.
2、PZT-5H vs PZT-5A
PZT-5A: Due to its high impedance, high sensitivity, and high stability at increasing temperatures, this product is mainly used in hydrophones or precision instruments.
model | Material | Kp | K31 | K33 | Kt | ε Tr3 | Tg δ% | d31 (-10-12m/v) | d33(-10-12m/v) | g31(-10-3m/v) | g33(-10-3vm/n) | Se11(-10-12m2/n) | Qm | V | ρ(103kg/m3) | Tc(℃) | YE11﹤109N/m3 | σ E |
PZT-50HD | 5A | 0.63 | 0.37 | 0.71 | 0.49 | 1950 | 1.5 | -191 | 430 | -11.1 | 25 | 15.4 | 90 | 2860 | 7.9 | 365 | 65 | 0.31 |
PZT-5H: Has higher sensitivity and dielectric constant than PZT-5A, and other properties similar to PZT-5A, but its Curie temperature is significantly lower than PZT-5A, thus its temperature stability is limited.

PZT-53HD | 5H | 0.71 | 0.42 | 0.74 | 0.52 | 3850 | 2 | -300 | 680 | -8.8 | 19.9 | 15.1 | 65 | 2890 | 7.9 | 230 | 66 | 0.3 |
Both PZT-5H and PZT-5A are piezo soft material. Some of company named it as navy VI and navyII. In He-Shuai company ,our model 5H is 53HD, 5A is 50HD.
3、Characteristics of PZT-5H
PZT-5H is soft piezo material, also called navy VI.
Our company(he-shuai) model is PZT-53HD
4、Application of PZT-5H
PZT 5H is commonly used in various applications, such as in sensors, transducers, and actuators that operate at high temperatures. It is also used in non-destructive testing, ultrasonic cleaning, and high-frequency medical imaging applications.
5、The application case of He-shuai company PZT-5H
