Supply Wear Resistant Alumina Ceramic Industrial Mechanical Ceramic
Alumina can be produced in a range of purities with additives
designed to enhance properties. A wide variety of ceramic
processing methods can be applied to produce a wide variety of
sizes and shapes of component, such as dry pressing, cold isostatic
pressing, hot press moulding technique, etc. In addition, it can be
readily joined to metals or other ceramics using metallising and
brazing techniques.

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.
