Electrodes

We supply graphite and carbon electrodes for electric arc furnaces, ladle furnaces and foundries.

Trusted across North America, our electrodes have performed reliably under high temperature with excellent conductivity, low oxidation, and high resistance to thermal shock.

We work upstream with our suppliers to ensure the quality of raw material they use. We then rigorously examine the machining both with our suppliers and with independent third parties to minimize chance of error.

  • Diameters range from 8" to 24" (177mm to 612mm)
  • Lengths range from 72" to 110" (1800mm to 2700mm)
  • Full range of grades for electrodes: HD, HP, FG, SHP, and UHP
  • All pins are UHP quality
  • Our sockets and pins align with NEMA standards
