Tungsten Copper Sheet
Copper tungsten sheet, copper tungsten plate, block and bar are very popular used as EDM electrode. This material has both tungsten and copper's characters, for example: copper is good for electrical conductivity, tungsten is good for the hardness. Copper tungsten plate for EDM is made by vacuum infiltration technology, which has very good physical and mechanical properties.
Copper tungsten sheet has below advantage for EDM
-
Maturity press- sinter- infiltration process.
-
high electrical conductivity get high erosion speed.
Tungsten Copper Sheet Applications
* Electrodes in electric spark erosion cutting machines
* Heat sinks as passive cooling elements of electronic devices
* Electrodes for Resistance Welding
