Product description

Product Description:


99% Alumina High Polishing Ceramic Rod With Screw



Alumina Ceramic Rods have a high melting point, high hardness,although mechanical strength is reduced at temperatures above 1000 C. Due to the relatively large coefficient of thermal expansion, thermal shock resistance is reduced. So it is widely used for many mechanical parts which request very high temperature.

We can provides all kinds of shape ceramic part, such as rings, rods, tubes, plates, inserts, bushing, sleeves, blocks, plunger and so on.



Properties Sheet:

The products are made of zirconia ceramic and alumina ceramic material, which have advanced and excellent performances.

Advantages of Zirconia ceramic insulation tubes:
 
1. Refractory.
2. Self Lubricating.

3. Long Service Life.
4. Good Polished Surface.

5. Environmental and Healthy.
6. Superior Mechanical Strength.
7. High Corrosion and Wear Resistance.
8. Good Insulation Performance Precision.
9. High Temperature and Pressure Resistance.
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.
