Brief Introduction
Graphite Electrode
Graphite electrodes are widely used in steel, non-ferrous, silicon and phosphorus melting industry. Good electrical conductivity, high resistance to thermal shock and low oxidation at elevated temperatures.
Our graphite electrode is being carried out with the strict quality control and the products will meet the exacting industrial requirements.
