EDM electrode
Copper Tungsten Electrode In view of tungsten steel, high
temperature super-hard alloy die to be produced by corrosion, the
common electrode wear big, slow, and the W-Cu electrical corrosion
of high speed, low loss rate, precise electrode shape, excellent
processing performance, to ensure the accuracy of processing pieces
of greatly increased.
Copper Tungsten Electrode Picture:
High-voltage electrode discharge tube
High-voltage vacuum discharge tube in the workplace, the contact
material in a few seconds of time zero temperatures thousands of
degrees Celsius, while the W-Cu anti-ablation properties, high
toughness, good electrical conductivity, thermal conductivity
performance to the discharge tube to provide the necessary
stability conditions.
Electronic Packaging Materials
Both the low-expansion properties of tungsten, but also has high
thermal conductivity properties of copper, its thermal expansion
coefficient and thermal conductivity of conductive material can be
adjusted to change the composition and thereby to the material
provided to facilitate the use.
