EDM Electrodes Tungsten Copper Alloy Electrodes Diameter 1.0mm to 30mm W80Cu20
Because tungsten copper alloy has heat resistance and wear
resistance of tungsten and high conductivity of copper, this
composite material has high hardness, high softening temperature,
good conductivity, easy processing and other excellent
characteristics. Tungsten copper has several major series: "E"
series for EDM electrode; " R" series for resistance welding
electrode; "W" series for weight; "G" series for electric contact
head and contact spot.
The high physical and mechanical properties, as well as the thermal and electrical conductivity, of refractory metal composites make tungsten copper alloy very suitable for die inserts and electrode facings, flash and butt welding dies, and hot upsetting. They can also solve heat balance problems.
