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:
- Q: What are the products you mainly work on?
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.
- Q: Can you accept product customization?
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.
- Q: Can you deliver the goods via our courier agent?
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.
- Q: How can you guarantee we get what we want safely?
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.
- Q: Can we visit your factory?
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.
Acceptance Check
- The product is fragile. We have adequately packed it and labeled it
fragile. We deliver through excellent domestic and international
express companies to ensure transportation quality.
- After receiving the goods, please handle with care and check
whether the outer carton is in good condition. Carefully open the
outer carton and check whether the packing boxes are in alignment.
Take a picture before you take them out.
- Please open the vacuum package in a clean room when the products
are to be applied.
- If the products are found damaged during courier, please take a
picture or record a video immediately. DO NOT take the damaged
products out of the packaging box! Contact us immediately and we
will solve the problem well.
