copper tungsten rod
Classification :
Copper Tungsten alloy
Description :
The manufacturing process is as follows: press the refractory metal, sinter the pressed compact at a high temperature, and infiltrate it with copper. All this is done under very closely controlled conditions. The result is a relatively hard material with superior arc and wear resistance, high physical Properties: at elevated temperatures, and good electrical and thermal conductivity.

copper tungsten rod
The manufacturing process is as follows: press the refractory metal, sinter the pressed compact at a high temperature, and infiltrate it with copper. All this is done under very closely controlled conditions. The result is a relatively hard material with superior arc and wear resistance, high physical Properties: at elevated temperatures, and good electrical and thermal conductivity.
Commonly used copper tungsten mixtures contains 10–50 wt.% of copper, the remaining portion being mostly tungsten. The typical properties is dependent on its composition. The mixture with less wt.% of copper has higher density, higher hardness, and higher resistivity. The typical density of CuW90, with 10% of copper, is 16.75 g/cm3 and 11.85 g/cm3 for CuW50 . CuW90 has higher hardness and resistivity of 260 HB kgf/mm2 and 6.5 μΩ.cm than CuW50.
