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.
