Strong Hardness Insulating Ceramic

Product Description

Alumina Ceramic Slat Positioning Ceramic Plate Insulating Ceramic


    Alumina ceramic bar is developed and made of Aluminum Oxide (Al2O3). Alumina is widely used in structural, electronics, medical and electrical fields as one of the most important ceramic oxides. 


    Alumina ceramic parts are often used during high temperature demanding and contamination-free reactions. It’s also a good electrical insulator used as a substrate for integrated circuits. Considering alumina’s price, high melting and boiling points, good resistance, strong hardness and good electrical insulation, alumina is widely spread and used all over the world in lots of industries.

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. Can you do the finish maching?

    Yes, we have lathes, grinding machines, milling machines, carves-milling machines to make sure products' accuracy.


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. 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. Which is the nearest port?

    Shanghai port is the nearest one from us. It takes about 2-3 hours to get to shanghai port.
