Product Description

99% Yellow Alumina Ceramic Tube Ceramic Protective Sleeve Supplier


    Alumina is the most widely used technical ceramic and is the material of choice in about 80% of engineering applications due to its excellent combination of properties. Sintered at over 1600°C (2910°F) to give a fully dense ceramic, Alumina exhibits high mechanical strength and stiffness which is retained even at elevated temperatures.


    Alumina tubes and rods are found across numerous user industries as a cost-effective yet high-performance solution. The combination of key properties makes them a good choice in many instances:


  • Thermally stable – Alumina can be used in both oxidizing and reducing atmospheres up to 1600°C (2910°F) and in vacuum furnaces up to 1750°C (3180°F).
  • Fully dense – Alumina provides a non-permeable tube that protects from contamination and can be used to create a gas-tight assembly.
  • High chemical resistance – Alumina is chemically inert and not corroded by water or steam. It offers good resistance to corrosive substances such as strong acids or alkalis, even at elevated temperatures.
  • Electrical insulation – Alumina is also widely used as an electrically insulating material. It can be used for insulators operating at elevated temperatures (e.g. furnace lead-in tubes, fuel-cells).

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.
