Shenzhen Customized Machinable High Purity Ceramic Alumina Sheet for Industry
Description of alumina ceramic sheet
Alumina ceramic sheets can withstand high temperature, high voltage, high current and strong chemical harsh environment, also it offers high strength and hardness and low thermal expansion. So it has a very wide range of applications in a variety of electrical, electronic, chemical, power and so on.
We have various sizes of finished shapes in stock and are able to conduct custom manufacturing for all kinds of alumina components.
The prime characteristics of the alumina ceramic sheet:
1, High-Temperature Resistance, high Wear-resistance
2. Good smoothness/flatness with a full dense body.
3. Minimal warpage, bending, and undulation.
4. Physical and chemical properties are stable even in a harsh environment.
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.
