Isostatic Graphite Electric Discharge Machining EDM Graphite Electrode Black

EDM Graphite Electrode with 3-5 Times Faster Machining Speed, 1/5 Weight of Copper, and 3650°C High Temperature Resistance for Precision Molds


Comparison ParametersAdvantages
Production costsGraphite of the same volume costs only about 25% that of copper electrodes.
Machining SpeedThe machining speed is 3–5 times faster than copper electrode, the machined surface is smooth. The electric discharge machining speed is 1/3 to 2 times faster than that of traditional copper electrodes, making it more suitable for rough machining.
Machining accuracyGood machining precision, C.T.E is 1/4 of copper, easy polishing.
WeightThe density of graphite is only 1/5 of copper, it's more suitable in the production for larger electrode.
LossUsed as EDM electrode, which consumption is only 1/3–1/5 of copper electrode, the coating of spark decomposition of carbide compensates electrode loss.
High temperature resistanceThe melting point of graphite is up to 3650℃, with no deformation under high-temperature working conditions, and more suitable for machining bone electrode.
Electrode CohesivenessDamaged graphite parts can be bonded with conductive adhesive, effectively saving production time and reducing material costs.
