Navy Type I

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, nano-positioning, and medical therapeutics.

Navy Type II

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

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

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.
