99% Alumina Ceramic Round Plate Fine Ceramic Plate Alumina Ceramic
Disc
Alumina ceramic is the most mature of the engineering ceramics,
with excellent electrical insulation properties, high hardness and
good wear resistance, but relatively low strength and fracture
toughness.
We can make engineered ceramic, strengthened structure ceramic,
ceramic bar, ceramic tube, ceramic block, ceramic ring, ceramic
cylinder, ceramic bushings, ceramic shaft, ceramic plate, ceramic
sleeve, ceramic plunger and ceramic arm, ceramic pin, etc.

Yes, we're a factory producing industrial ceramics professinally,
with more than 10 years experience.
2. What's your main products?
Our main products are alumina ceramics, zirconia ceramics and sic
ceramics.
3. What's the size of it?
Products are always customized according to drawings or samples.
Diameter and height within 500mm are available.
4. What's the price for it?
It depends. Prices are caculated by the drawing size and structure.
5. How about the delivery?
Generally speaking, a ceramic production needs about 30 days to
finish. Some special products maybe take a longer time. For some
simple products, maybe 10-15 days is ok.
6. Can you do the finish maching?
