Aluminum Oxide is a solid chemical compound of aluminum and oxygen and is the most commonly occuring form of aluminum oxides. Commonly called alumina, it is an outstanding ceramics material due to it’s hardness and high melting point.
Aluminum Oxide is the most commonly used material in technical ceramics, and the chemical, medical and wear industries. It is available in a variety of purities and has an excellent cost-to-material performance record, making it a suitable choice for selected wear liners, mechanical pump seal faces, insulators and other electrical applications.

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 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. Hot press moulding technique, which was used to shape small and medium size and complicated structure ceramic, is a favorable method.
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.
