Tungsten copper W80 rod 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).
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.
Tungsten copper W80 rod can be used as missile nozzle or rocket insert and jet vane at high temperature.
| The standard length of tungsten copper W80 rod we are able to provide is less than 300(0,+5)mm, and the diameter is Ø1±0.5mm, customized sizes and tolerances are also accepted.
