Hard PZT

Pz89 is a dedicated high-power PZT material that serves as a direct substitute for all Navy III materials. Its crystallographic structure enables it to withstand greater mechanical stress than other hard PZT materials without depolarizing, making it a good choice for applications where power output must be maximized.
