High Power Hard Piezoelectric Ceramics

Our high density hard PZT materials perform when your applications demand the most.

From standard materials to custom formulations, our “hard” piezoceramics are engineered with highly dense microstructures with improved electrical and mechanical properties. These materials provide more than just low dielectric and mechanical losses; they provide a strength that results in yields above 90%.

  • Improved dielectric and piezoelectric properties
  • Enhanced machinability increases production yield and reduces costs
  • High sensitivity and temperature stability in a robust package

Applications and Advantages

  • Sonar arrays
  • Tubes for therapeutic ultrasound and HIFU
  • Shock resistant for sensors
