Customized ceramic shaft rod good heat conductivity



High precision ceramic shaft rods we produce have good heat conductivity , high thermal conductivity. we offer custom ceramic shaft rod with multi sizes and shape due to the ceramic shaft have a wide range use for industry which have own sizes demands and diameters.

 

Advantages of ceramic shaft rod:

- High thermal conductivity
- Low coefficient of expansion 

- High strength
- High temperature resistance
- Chemical resistance
- High resistivity
- Small dielectric constant
- No toxicity
 

Note: 1.Surface roughness can be reached 0.1μm after polished.

           2.Size tolerance can be controlled in +-0.10mm with laser machined.

           3.Special specifications can be supplied upon requests.
