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.
