Which is more conductive, graphite electrode or copper?

1, which can reduce the number of single electrodes and make combined electrodes.

2, an electrode clamp system can be omitted, and the cost is saved.

3. High-speed milling is 3 times thicker than copper block and has good machinability. Complex geometric modeling can be realized.

4, light weight, its density is less than a quarter of copper. Good thermal stability, no deformation. Without deburring, electricity can be clamped easily.

Copper electrode:

1, copper has good toughness and heavy weight.

2. Copper will be deformed and difficult to process.

3. The electrode loss in finishing is small, and the machined surface can reach Ra≤0. 1 μm, which is suitable for mirror machining. If there are lines on the surface, these lines are etched with copper.
