Quartz Wafers: SAW Grade Synthetic α-Quartz
Jingxin New Materials supplies SAW grade synthetic α-quartz wafers with extremely low temperature coefficient and high Q value, for frequency control and timing applications.
Synthetic α-Quartz Wafers
Our quartz wafers start from qualified synthetic α-quartz material, sourced and verified before entering our in-house slicing, lapping, polishing and inspection line. The material offers an extremely low temperature coefficient and high Q value — properties that make it the substrate of choice for frequency-critical and timing applications where temperature drift must be minimized.

Available Cut Types
Each cut type is made by rotating the quartz plate a specific angle relative to the crystal's X, Y and Z axes. Different rotation angles produce different vibration modes, frequency ranges and temperature-stability characteristics. The eight cuts below are our current standard offering — other cut angles can be produced to order, so if your design calls for a cut not listed here, contact us to confirm feasibility.
1–300 MHz. The most widely used cut — best overall temperature stability and cost.
10–70 MHz. Thicker than AT at the same frequency — more mechanically robust.
50 MHz–3 GHz. Optimized for surface acoustic wave devices, not bulk resonance.
0.5–200 MHz. Low sensitivity to mounting stress and thermal shock — OCXO standard.
1–200 MHz. Between AT and SC — faster warm-up at high ambient temperatures.
30–100 kHz. Low frequency constant — suited to large, low-frequency plates.
100–500 kHz. Mirror counterpart to CT-cut, with fewer spurious modes.
100 kHz–3 MHz. Flattest frequency-temperature curve of any quartz cut, wide temp range.
Angle values shown are standard reference figures for common quartz cut types; IT-Cut's precise rotation angle is not independently confirmed and is shown without a specific figure. Diagrams illustrate the general slicing concept and are not to exact scale. These eight cuts are our current standard offering — additional cut orientations can be produced to order; contact us for datasheet-level specifications on a specific or custom cut.
| Cut | Rotation | Vibration Mode | Typical Frequency Range | Core Advantage |
|---|---|---|---|---|
| AT | Singly-rotated Y (+35°15') | Thickness-shear | 1–300 MHz | Best overall cost / temperature stability |
| BT | Singly-rotated Y (-49°00') | Thickness-shear | 10–70 MHz | Thicker plate, higher mechanical strength |
| ST | Singly-rotated Y (~+42°45') | SAW | 50 MHz–3 GHz | Zero-TC cut purpose-built for SAW devices |
| SC | Doubly-rotated (Φ≈22.4°, θ≈34.1°) | Thickness-shear C-mode | 0.5–200 MHz | Stress and thermal-shock resistant, OCXO grade |
| IT | Doubly-rotated (angle TBC) | Thickness-shear | 1–200 MHz | Faster high-temperature warm-up vs SC |
| CT | Singly-rotated Y (+38°00') | Face-shear | 30–100 kHz | Low-frequency constant for large plates |
| DT | Singly-rotated Y (-52°00') | Face-shear | 100–500 kHz | Fewer spurious modes than CT |
| GT | Rotated + precision width/length ratio (~+51°07') | Dual width-extensional | 100 kHz–3 MHz | Flattest temperature curve of all quartz cuts |
