Custom Large Size Alumina Porous Ceramic Disc Plate

Product Description:

Custom large size alumina porous ceramic disc plate

Alumina (Al2O3) has a wide application due to its versatility and low material cost. Alumina possesses 

a high melting point, strong hardness, and good chemical stability, making it a good material to withstand 

high temperature and chemical corrosion. Alumina Plates and Disks are available in different dimensions 

and thicknesses. Call for custom shapes and sizes.

Properties Sheet:

The products are made of high purity zirconia ceramic and alumina ceramic material, which have 

advanced and excellent performances, fabulously popular.

10. High Purity Zirconia and Alumina Ceramic Material.

• High hardness, long service life, not easy to break and wear resistance.
• Non-conductive, anti-static, ceramic material itself with the insulation of electricity and magnetism properties.
• Corrosion resistance, high temperature resistance, can be applied to a specific environment, such as acid and alkali resistance.

Production process:

One-stop production, from the raw material (powder) to final products, control the quality strickly of every production link.

Packaging and Shipping:

High temperature ceramic disk will be packed in a bubble bag individually, then separated by a foam, 

finally put in standard export carton packing, or OEM packing.
 
Shipped by Express ( DHL, TNT, UPS, Fedex, EMS ), Air, or Sea transportation.
