Graphite electrodes are characterized by low resistance, good electrical conductivity and thermal conductivity, high resistance to oxidation and thermal shock, high mechanical strength, etc. According to its high quality and low quality, it can be divided into ordinary power graphite electrode, high power graphite electrode and ultra-high-power graphite electrode.
Advantages:
1.Anti-oxidation treatment for longevity.
2.High-purity, high-density, strong chemical stability.
3.High machining accuracy, good surface finishing.
4.High mechanical strength, low electrical resistance.
5.Resistant to cracking & spalling.
6.High resistance to oxidation and thermal shock.
