Tungsten Copper W80 Block

Tungsten copper W80 block is composed of 80% W and 20% Cu so that high hardness and melting point characteristics of tungsten is more obvious. Its density is up to 15.15g/cm3, hardness reaches more than HB140, but due to less Cu, conductivity is decreasing to 34%IACS, softening temperature is ≥900℃,the bending strength is 980, the thermal conductivity is 190-210(wm/k) and the coefficient of expansion is 8.0-8.5(10-6K).

In the early 1960s, american researchers have been used tungsten copper as missile nozzle or rocket insert and jet vane at high temperature. Common materials could not work at such high temperature (even more than 3000℃), tungsten copper takes advantage of Cu evaporating taking away heat so that the whole temperature will decrease.

Therefore, tungsten copper can be widely used in rocket, missle and some parts for high temperature, high speed air flow erosion or scouring, such as jet vane, spray tube, throat insert and so on. In addition, it can be also used in liner of shaped charge of EFP. With the rapid development of Aeronautics, the requirements of tungsten copper will increase gradually. And It should be noticed that adjust the parameters when tungsten copper discharging or wire cutting, and the speed is lower than other materials. To avoid contacting with strong acid and alkali before electroplating, which will cause the metal grain shedding.
