Piezoelectric ceramic hemisphere 

Electrode direction: Radial direction

Custom piezo sphere 

 

 

 

Hard PZT

High power or "hard" PZT ceramics can withstand high levels of electrical excitation and mechanical stress. These materials are suited for high voltage or high power generators and transducers.

Pzt-4 Series

This material range is ideally suited for ultrasonic cleaningsonar, and other high power acoustic radiation applications. These materials are designated as PZT-4 series type materials and are capable of producing large mechanical drive amplitudes while maintaining low mechanical and dielectric losses. In addition, it can be used under both constant and repetitive conditions. Yuhai company offer a complete range of three PZT-4 series material types with a variety of permittivity values, coupling, power handling and actuation properties.
