Navy Type I is suitable for both constant and repetitive conditions in sonar,

ultrasonic cleaning, and other high power applications. This material

produces large mechanical drive amplitudes while maintaining low

mechanical and dielectric losses. Applications include STM, nanopositioning,

and medical therapeutics.

Navy Type II has high sensitivity, permittivity, and time stability in

applications when used as the receiver or generator element in

accelerometers, vibration pickups, and hydrophones. Applications include

flow and level sensing and medical Doppler transducers.

Navy Type III is used in high power applications and has an extremely

high mechanical quality. With the ability to withstand high levels of

electrical excitation and mechanical stress, Navy Type III has the best power

handling capabilities. Applications include ultrasonic cleaners, cell

disruption, phacoemulsification, and high power ultrasonics.

Navy Type VI has very high permittivity, coupling, and piezoelectric

constant, but lower time stability. It is used in applications requiring fine

movement control or for sensitive receivers. Its low Curie temperature

restricts its operating temperature range. Applications include medical

diagnostics, industrial NDT, STM/AFM, and nano-positioning.

Our company also supply other piezoelectric materials. Thanks!
