Low shrinkage and low thermal conductivity round alumina ceramic plate
1. Description
Alumina ceramic is widely used in many fields. Because of its great performance, it is more and more used in curent society, alumina ceramic substrate can meet the requirement of daily using and specifical features.
We manufactures custom technical ceramics, covering a wide range of customer requirements .We make use of several forming and machining techniques to process components made from alumina Ceramics, This material may be used in applications that require High elevated temperatures ,High dielectric strength, excellent electrical resistance . wear or corrosion resistance .high temperature capability .High Electrical insulation.
2. Main Features
1. Can be made into various of complex shapes, high dimension accuracy.
2. Contact with flame directly,no odor and volatile gases at high temperatures
3. High mechanical strength,resistance to gas flow.
4. Low shrinkage,low thermal conductivity.
5. Excellent strength in high temperature and thermal stability.
