Piezoelectric Discs for Atomizers, Sensors & Cleaning
Yujie manufactures PZT piezoelectric discs for ultrasonic atomizers, nebulizers, beauty devices, sensors, and patch-type cleaning modules. Compare disc diameter, thickness, frequency, impedance, and coupling coefficient before choosing a ceramic disc for your OEM ultrasonic device.
Features & Applications
Core Applications & Technical Advantages
- •Ultrasonic Atomizers & Nebulizers: HJ-25/1.65M and HJ-20/1.65M deliver 1.65 MHz frequency for ultra-fine mist generation with impedance as low as 2.0Ω
- •Beauty & Skincare Devices: H-series discs (Ø20-28mm) optimized for 1.0 MHz facial cleansing and treatment equipment
- •Patch-Type Ultrasonic Cleaners: HJ-50 series with 45 kHz frequency and high coupling coefficient (0.58) for adhesive-mount cleaning applications
- •Medical & Laboratory Equipment: Precision-manufactured PZT discs meet stringent requirements for medical nebulizers and diagnostic tools

Piezoelectric Disc Technical Specifications
Use this table to match a piezoelectric disc to the buyer intent behind searches such as piezoelectric disc, PZT disc, atomizer piezo disc, and ultrasonic cleaning disc. Specifications are measured at 25°C ±2°C ambient conditions.
Preparing an RFQ for Custom Piezo Discs
A complete disc enquiry answers six questions on one drawing: outer diameter and its tolerance, thickness and its tolerance, electrode pattern (full-face, wrap-around, or custom), silver or alternative metallisation, material grade, and the resonant behaviour you expect in the finished device. Quotes against a full drawing are typically faster and firmer than iterative email threads.
Grade selection follows the duty: hard compositions suit sustained high-drive duty, while soft grades favour sensing and low-drive actuation — the trade-offs are documented on the PZT material hub. If you are replacing an existing disc, sending the incumbent part's marking and measured dimensions lets our engineers propose a like-for-like or improved match.
For new designs, expect a sample stage before volume: poling direction, electrode wear under your soldering process, and batch consistency are verified on real parts, not datasheets.

Use these links when the disc selection discussion moves beyond geometry and into aerosol reliability, sourcing risk, and production control for nebulizer transducers.
High-Frequency Expertise
MHz-range piezoelectric discs are available for suitable atomization and sensing projects. Frequency, material, geometry, and assembly conditions are reviewed together.
Precision Manufacturing
Grinding and lapping requirements are reviewed against the target frequency and assembly. Achievable thickness tolerance and flatness are confirmed for the selected material and drawing.
Quality Testing
Inspection may include dimensions, capacitance, loss, impedance, frequency, or other agreed parameters. Sampling and available reports are confirmed during quotation.
Application Support
We support piezoelectric disc selection, driver and assembly discussions, and sample planning for qualified projects.
