Copper Tungsten (20%Cu-80%W) Alloy Rod Bar Per Kg Price

1.the applications of copper tungsten alloy rod :sealed cap for transistors sealing welder,contactor materials for highvoltage switches and electrodes for spark processing etc.

Commonly used copper tungsten alloy contains 10–50 wt.% of copper, the remaining portion being mostly tungsten. The typical properties of the alloy depend on its composition.

The alloy with less wt.% of copper has higher density, higher hardness and higher resistivity. The typical density of CuW90 alloy, with 10% of copper, is 16.75 g/cm3 and 11.85 g/cm3 for CuW50 alloy. CuW90 has higher hardness and resistivity of 260 HB kgf/mm2 and 6.5 µΩ.cm than CuW50.

Copper Tungsten Alloy Rod Applications:

· Arc contacts and vacuum contacts in high/medium voltage breakers or vacuum interruptors

· Electrodes in electric spark erosion (EDM) cutting machines

· Heat sinks for passive cooling of electronic devices

· Electrodes for resistance welding
