Tungsten Copper Military

Tungsten copper military material is fabricated from the two mutual indissolvable metal of tungsten and copper, which combines the properties of good hardness, high melting point and low coefficient of thermal expansion of tungsten with copper’s of high conductivity and high thermal conductivity, it is a kind of well performance composite. Copper tungsten military material not only has good thermal conductivity and low thermal expansion coefficient, but also can design its thermal conductivity and coefficient of expansion by changing its tungsten copper content.

Tungsten copper military alloy is easy to be machined. And with this series of fine characteristic, so copper tungsten military has been widely used in mechanical, electrical, instruments and other civil industrial, and also is widely in making important as well as complex components for aviation, spaceflight, weapons in the military industrial.

The theory of copper tungsten military materials applied as high temperature material in military use is that when the air temperature is close to event exceed the temperature melting point of tungsten (over3,000 ℃), the content of copper in tungsten copper materials evaporate and then absorb a great deal of heat , which greatly reduce temperature of tungsten copper military made parts. The table below shows the properties of high temperature tungsten copper.

Few materials could continue working in such high temperature. Therefore, one of the important use of tungsten copper military material is as high-speed and high temperature airflow ablation and flushing parts in rockets and missiles, such as gas helm, nozzle, throat lining, the nose cones, etc. In addition it still can be used as a medical cover of tank, the tailpipe and orbit materials of electromagnetic gun. With these applications, copper tungsten military materials should be handled strictly as the following two items.

In order to guarantee the properties of high temperature strength, good resistance to ablation, and erosion resistant of tungsten copper military material in high temperature ,it must be sure the high density of framework and skeleton intensity of tungsten, therefore, copper tungsten militarymaterials in this application generally contain 5% to 10% copper .

And for the sake of making the tungsten copper military materials gasification and smoothly reduce the material surface temperature by absorbing large mass of heat, it must be ensure that tungsten skeleton pore have very good connectivity and good capillary function at low copper content.
