Tungsten Copper Military

The theory of tungsten copper 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.

Few materials could continue working in such high temperature. Therefore, one of the important effects 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, tungsten copper alloy 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, tungsten copper alloy military materials in this application generally contain 5% to 10% copper . And for the sake of making the tungsten copper alloy 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.
