Our graphite electrodes are with low electric resistance, high density, high anti-oxidation capability, precise machining accuracy, especially with low sulphur and low ash will not give steel second time. 1. Low electric resistance 2. High density 3. Good electrical conductivity 4. High anti-oxidation capability 5. Precise machining accuracy 6. Low sulphur and low ash, not give steel second time impurity
