Product Description

Custom Thin 96% 99% 99.6% Ceramic Al2O3 Alumina Wafer for Microwave Components

Description of alumina ceramic sheet

Alumina wafer is one of the most popular ceramic wafers which has excellent heat resistance, high mechanical strength, abrasion resistance, and small dielectric loss. The surface of the alumina wafer is quite smooth and without porosity, 99.6% alumina substrate is suitable for the thin-film device, 96% alumina substrate is suitable for thick film device application. We provide alumina ceramic wafer for a wide range of applications, including thin film and thick film microelectronic, high power and high-frequency circuit RF/microwave components and capacitor or resistor. The typical thickness we offer is 0.30mm, 0.4mm, 0.50mm, 1.0mm and so on.

We have the capability in producing small to large size ceramic alumina wafers, whatever, it's a prototyping case or high volume project, we could provide you an ideal solution. 

The prime characteristics of the alumina ceramic wafer:
1. Good smoothness/flatness with a full dense body.

2, High-Temperature Resistance, high Wear-resistance

3. Physical and chemical properties are stable even in a harsh environment.

4. Minimal warpage, bending, and undulation.

5. Excellent thermal shock resistance. High thermal conductivity and coefficient of thermal expansion similar to that of silicon.

6. Excellent electrical insulation properties, high dielectric breakdown voltage.

7. Excellent resistance against oil and chemical.

8. Stable breaking strength, and less variance in shape or dimensions.
