6”Piezoelectric Wafer The Perfect Solution for Navigation Broadcasting and Time Control
Single-crystal quartz wafers are precision-engineered components that offer unparalleled performance in a wide range of applications. These wafers, made from the purest quartz crystal, offer excellent frequency stability, mechanical strength, and thermal resistance.
With their high piezoelectric properties, quartz wafers are ideal for use in oscillators, resonators, and sensors, ensuring accurate and reliable performance in timing and frequency control applications. Their resistance to thermal expansion and contraction means they maintain stability even in extreme temperature environments.
From telecommunications to aerospace, single-crystal quartz wafers are the choice of professionals who demand precision and durability. Upgrade your technology with the best — choose single-crystal quartz wafers for superior performance and reliability.

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.
