EDM Graphite Block Carbon Material with Good Lubrication Industrial Applications Mold

Product Description

Graphite block is made of domestic petroleum coke, with carbon content above 99%.  We have vibrated,molded and isotropic graphite block.  They are widely used in such fields as mechanical , electronics, chemical industry and other new industries.  

We can machine to specific shapes according to customers' requirements.

1.Good electric conductivity and high thermal conductivity

2.Low thermal expansion and high resistance to thermal shock.

3.The strength increases at high temperature, and it can withstand over 3000 degrees.

4.Stable chemical property and hard to react

5.Self lubrication

6.Easy to process
