JC4 Graphite Rods


JC4 is a strong fine-grained rod that is machinable and rated to a medium temperature (1355℉ | 735℃ Heat Treating). It’s properties allow for good density and strength when higher temperatures are not required. Typically these rods are used for mechanical applications. If you are operating at a higher temperature, please review our JC3 Graphite Rods.

  • Machinability to exceptionally close tolerances.
  • Good Thermal Conductivity as graphite is an excellent heat conductor and has great resistance to thermal shock.
  • High Compressive Strength ranging from 11K-38K lbs/in²
  • Corrosion Resistance for all practical purposes and is unaffected by most acids, alkalis, solvents, and similar chemicals.
  • Seal face flatness due to the high modulus of elasticity and stability to remain flat during operation at the rubbing faces.
  • Built-in Lubrications and Non-Galling. Products will not seize or gall in the most severe applications as the molecular structure of graphite forms an extremely thin film on moving parts.
  • Porosity. Graphite can be porous but impregnants are used to fill these pores and can range from high to totally impervious depending on need. Check out our GraphiSeal.


  • Heat Treating applications.
  • Used to support hearth rails or beams to allow for thermal expansion.
  • Fixtures or support post.
  • Electrodes, stir sticks, and other reaction purposes.
