Supply Wear Resistant Ceramic Industrial Structual Alumina Ceramic
Aluminium Oxide (Alumina) is a widely used ceramic material with
many excellent properties. They are grouped together based on
purity levels, as the purity of Alumina’s increases, wear and
corrosion resistance also increases. Alumina Ceramics are widely
used because of their chemical stability, which they maintain at
high temperatures. It is a material that is resistant to acids,
alkaline, and other chemicals.

FAQ:
1. Are you a factory?
Yes, we're a factory professinally producing industrial ceramics.
Our main products are alumina ceramics, zirconia ceramics and sic
ceramics.
2. What's the size of it?
Products are always customized according to drawings or samples.
Diameter and height within 500mm are available.
3. What's the price for it?
It depends. Prices are caculated by the drawing size and structure.
4. What's the production process?
Our products are made mainly in cold isostatic pressing, dry
pressing and hot press moulding technique.
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. How's the packing?
The usual packing is cartons, wooden cases, or pallets. Ceramics
are fragile products, will use some breakage-proof materials to
protect them.
7. Can you do the finish maching?
Yes, we have lathes, grinding machines, milling machines,
carves-milling machines to make sure products' accuracy.
8. Which is the nearest port?
Shanghai port is the nearest one from us. It takes about 2-3 hours
to get to shanghai port.
