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.
