Description of the al2o3 ceramic sheet

Al2O3, also known as alumina, is a hard-wearing technical ceramic material regularly used in a broad range of industrial applications. Al2O3 ceramic plates are frequently shaped by tape casting, dry pressed or Isostatic pressed and sintered under high temperature to be a strong and dense technical ceramic plates.

This kind of industrial ceramic plate can be made of different purity alumina ranges from 95% to 99.8%, also we are able to cater to various custom specifications, in addition to custom compositions for commercial and research applications and new proprietary technologies.
In order to reach some special application, like enhance the insulation strength, dielectric, precision assembly, we always proceed with these ceramic alumina plates with the secondary process with our in-housing manufacturing types of equipment, including diamond polishing, glazed surface, high precision dimensions, and super flat surface and metalized.

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


Typical applications of Al2O3 ceramic sheet
Power modules, LED packages, Substrates for chip resistors, HIC substrates for heat dissipation, FAX substrates for thermal printer head, Substrates for automotive parts, Substrates for general thick film application, Substrates for sensor parts, Substrates for electronic devices
