Alumina Ceramic Tube Inner Hexagon Mechanical Structual Ceramic
Alumina is a widely well-known and commonly used fine ceramic
material. It has been used for decades in electrical components for
its high electrical insulation, and is widely used in mechanical
parts for its high strength, and corrosion- and wear-resistance.

Applications for alumina ceramics:
Alumina ceramics are used in a variety of general-purpose
applications, and their grade is chosen based on the application
environment. Higher purity Alumina ceramic can be formulated for
more demanding applications. Typical Applications Include: Wear
resistant components, High pressure nozzles, Thermocouple tubes,
Electrical Insulators, Corrosive labware, Furnace fixtures,
Ballistic armor, Thread guides, Laser Tubes, and Pump seals, etc.

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 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.
