Product Description

Product Description

Graphite blocks are made from domestic petroleum coke, and contain more than 99% carbon. We have vibrational, moulded and isotropic graphite blocks. We can machine specific shapes based on the customer's requirements.

 

Benefits of Graphite Blocks

• Graphite blocks are used to make capable, reliable products.
• Graphite blocks produce electrodes that exhibit high electrical conductivity properties as well as good refractory properties (for example, high thermal shock resistance and low thermal expansion).
• Graphite blocks exhibit high mechanical strength, high thermal conductivity, and high density.
• Graphite blocks are highly machinable.
• These materials are chemically stable and lightweight.
