Factory Supply 99% Insulating Alumina Ceramic Plate Precision
Ceramic
Alumina’s impressive technical profile and relatively low material
cost make it ideal for many large and small scale technical
applications.
Alumina ceramics are one of the preferred materials for
high-performance insulators, spacers, heat sinks, medical devices,
mounts and isolators in space-based projects, and many other
applications in extreme environments.
Aluminum oxide ceramics are also used in everyday applications like
spark plugs or abrasion-resistant tiles, or textile ceramic parts.

Aluminum Oxide Ceramic Plate
FAQ:
1. Are you a factory?
Yes, we're a factory producing industrial ceramics professinally.
Our main products are alumina ceramics, zirconia ceramics and sic
ceramics.
2. What's the price for it?
It depends. Prices are caculated by the drawing size and structure.
3. What's the production process?
Our products are made mainly in cold isostatic pressing, dry
pressing and hot press moulding technique. Hot press moulding
technique, which was used to shape small and medium size and
complicated structure ceramic, is a favorable method.
4. Can you do the finish maching?
Yes, we have lathes, grinding machines, milling machines,
carves-milling machines to make sure products' accuracy.
