Piezoelectric ceramic disc  

Quick delivery

wrapped arround electrode available

 

 

Yuhai company developped piezo disc elements of various sizes, this range is fabricated from more than 10 available piezoelectric material formulations according to high sensitive, temperatures etc applications. 

 

 

Applications includes: 

  • high driving piezo transducer

 

Features : 

  • Sizes from 3mm up to 200mm
  • Thickness from 1mm up to 10mm
  • Choice of metallisation (Silver, Nickel, Gold and others on request)
  • Wide choice of PZT formulations

 

 

Application: high power ultrasonic vibration transducer

Material:  PZT-82 (hard PZT, equal to PZT-8) 

 

 

P-82  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.
