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.
