Raw material of HP Graphite electrode
The main raw material of graphite electrode is petrol coke, in regular power graphite electrode, a little amount of pitch coke can be added into the raw material. Both petrol coke and pitch coke should contain no more than 0.05% of sulfur. During producing HP graphite electrode and UHP graphite electrode, needle shape coke should be added into raw material.

Product Picture
Applications of HP graphite electrode for induction heating
Heat treatment of metals: HP graphite electrodes are used in induction heating systems to heat treat metals and alloys, such as steel, aluminum, and copper.
Surface hardening: HP graphite electrodes are used to surface harden parts, such as gears and shafts, by inducing heat on the surface of the part.
Brazing and soldering: HP graphite electrodes are used to heat up the parts for brazing and soldering, which involves melting a filler metal to join two parts together.
Melting of non-ferrous metals: HP graphite electrodes are used in induction furnaces to melt non-ferrous metals, such as aluminum, brass, and copper.
Glass melting: HP graphite electrodes are also used in the glass industry for melting glass in induction furnaces
