Copper Tungsten Electrode
Copper tungsten electrode's symbol is WCu. It has good physical and mechanical properties, such as high thermal and electrical conductivity. As to its supply state, copper tungsten electrode can be offered in sintering, tuming, grinding and finishing.
The technique of copper tungsten electrode is copper infiltered tungsten block in vacuum high temperature stove. During processing, proportion of copper and tungsten can be 60W/Cu, 70W/Cu, 75W/Cu, 80W/Cu, 85W/Cu, and 90W/Cu.
There is a table to show its physical properties:
| Chemical content (%) | Density (g/cm3) | Resistance max µΩcm | IACS (%) min | Hardness (HB) | ||
| Cu | W | |||||
| 60W/Cu | 40 | 60 | 12.75 | 3.7 | 47 | 140 |
| 70W/Cu | 30 | 70 | 13.80 | 4.1 | 42 | 180 |
| 75W/Cu | 25 | 75 | 14.50 | 4.5 | 38 | 200 |
| 80W/Cu | 20 | 80 | 15.10 | 5.0 | 34 | 220 |
| 85W/Cu | 15 | 85 | 15.90 | 5.7 | 30 | 240 |
| 90W/Cu | 10 | 90 | 16.75 | 6.5 | 27 | 260 |
Copper tungsten electrode is widely used in sealed cap for transistors sealing welder, contactor materials for high-voltage switches, electrode for spark processing, circuit breakers, and etc.
