What Ultrasonic Cleaning Frequency Is Best for Parts and Jewelry?
Lower ultrasonic frequencies create larger, more energetic cavitation bubbles; higher frequencies are generally gentler and better suited to fine features. The common 40 kHz class is a versatile middle ground for many shop parts and jewelry applications.
Match frequency to the surface
Heavy carbon and robust metal parts tolerate a more aggressive process than delicate plated jewelry, optical parts or fine electronics. Frequency is only one variable; chemistry and time can be even more important.
Do not chase a number in isolation
A 40 kHz tank with good transducer placement and proper solution can outperform a poorly designed unit at another frequency. Start with the material and contamination, then choose the process.
What to check before buying
- Workpiece material/finish
- Type of contamination
- Nominal frequency
- Compatible cleaning chemistry
