Tungsten Copper W80 Rod

Introduction

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).

Characteristic

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. In addition, 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 and it will cause the metal grain shedding.

Application

Tungsten copper W80 can be used as rocket, missile and other components with high temperature and high-speed airflow ablation, such as gas vane, spray tube, throat insert, nose cone and so on. In addition, it also can be used as EFP linear of armor piercing, nozzle of range-extended, orbit material for electromagnetic gun. With the development of aerospace industry, the requirement of tungsten copper used for high-temperature will remarkably increasing, so it has higher demands for tungsten copper materials quality, especially the strength and ablation performance under high pressure and high temperature.
