copper tungsten for tungsten carbide EDM machining

EMD is the name of Electrical Discharge Machining. It is quiet new machining technology especial high efficiency for the hard material for example tungsten carbide, high speed steel, and PCD tools. Especially for the tungsten carbide machining is the challenge since it is very hard and consume the electrode.

HOSO METAL working in this field more than ten years. we dedicate to produce the tungsten copper electrode, chromium copper electrode, tungsten silver electrode for the EDM application.

copper tungsten bar electrode for tungsten carbide EDM machining

copper tungsten wire electrode for tungsten carbide small hole machining:

 HOSOPM® copper tungsten wire size range: Dia. 0.5x175mm, Dia. 0.6x175mm, Dia. 0.7x175mm, Dia. 0.8x175mm, Dia. 0.9mmx175mm, Dia. 1.0x175mm

The qualify electrode for EDMing should has below properties:

• High electrical conductivity

• wear resistance

• easy machining

HOSO METAL supply below material for the EDM

Material	advantage	Disadvantage
CuCr	hard, easy to machining	low electrical conductivity compare to copper
tungsten copper	good wear resistance, the best choice of high precise EDMing.	cost higher than pure copper
tungsten silver	the best choice of slim hole EDMing	cost higher than tungsten copper
