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 cleaning, sonar, and other high power acoustic radiation applications. These materials are designated as PZT-4 series type piezo 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.

PZT-82

This material range is used in high power applications, even though its piezoelectric activity level is slightly lower than PZT400 series types. With an extremely high mechanical quality factor and extremely low loss factor, PZT800 series materials have the ultimate power handling capability.

Hard piezo material exhibits: smaller piezoelectric constants, lower permittivity, smaller dielectric constants, lower dielectric losses, smaller electromechanical coupling factors, high mechanical quality factors, a higher coercive field, better linearity, and is harder to be depolarized.

The ideal application of hard piezo materials is high power transducer needs.
