Customize High Temperature Industrial 99% Alumina Ceramic Plate
Description:
Alumina ceramic plates are formed by tape casting, dry pressed or Isostatic pressed and sintered under high temperature to be a strong and dense ceramic part. We can produce different grades of materials to custom specifications by request, 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.

Advantages:
1. High purity:Good resistance of high temperature and abrasive.
2.Tight Tolerance. we can machine the alumina seal ring to make tight tolerance, good surface roughness and flatness.
3.Various processing methods, casting, preesing, grinding etc.
4.Inspection: each single alumina ring will be checked before shipping.
5.Low transportation cost : We have long time cooperated shipping agency, which can provide very low prices.
Application:
Alumina ceramic is mainly used in large power equipment, IC MOS tube, IGBT chip heat conducting insulation, high frequency power supply, communication, mechanical equipment, strong current, high voltage, high temperature and other thermal heat insulation parts need products.Physical properties.
