Unleash the Potential of Piezoelectric Quartz Ring with Piezoelectric Wafer for Precision Sensing Solutions
Our Piezoelectric Quartz Ring is a masterfully engineered component designed to harness the unique properties of quartz crystal for advanced technological solutions. Renowned for its exceptional piezoelectric effect—generating an electric charge under mechanical stress—this ring delivers unparalleled stability, frequency control, and sensitivity, making it indispensable in aerospace, telecommunications, medical devices, and precision instrumentation.
Crafted from premium-grade synthetic quartz, each ring undergoes rigorous polishing and lapping to achieve atomic-level surface precision and uniformity. Its low thermal expansion coefficient ensures minimal frequency drift, even under extreme temperature fluctuations, while its high mechanical Q factor guarantees long-term reliability and low energy loss.
Available in customizable diameters, thicknesses, and frequency ranges (kHz to MHz), our piezoelectric quartz rings are tailored to meet exacting specifications for oscillators, filters, sensors, and ultrasonic transducers. Backed by decades of expertise and ISO-certified manufacturing, we guarantee consistent quality and traceability.
Elevate your project’s performance with our Piezoelectric Quartz Ring—where cutting-edge precision meets industrial-grade durability.

FAQs:
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.
A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.
A: Sure. Factory inspection is important for large quantity purchase and long-term cooperation. Face to face discussion is what we mostly confident with. During the past years, big names around the world have witnessed our progress in factory build-up. These days, due to the Covid-19 pandemic, we also had the experience of videoconferencing with global buyers.
