The heat resistance of tungstan-copper alloy is not as good as that of tungstan-copper, but it is better than some heat-resistant materials, so its application prospect is good. Because the wettability of molybdenum-copper is worse than that of tungstan-copper, especially when preparing molybdenum-copper with low copper content, the density of the material after melting is low, resulting in the material's air tightness, electrical conductivity and thermal conductivity can not meet the requirements, and its application is limited.

Copper oxide powder is not metal copper powder, copper forms a continuous matrix in the sintered billet, tungsten is used as a strengthening frame, the high expansion component is restricted by the second component around, the powder is sintered in wet H at a lower temperature, according to the initial use of very fine powder, can improve the sintering performance and densification, so that it can reach more than 99%.

Tungsten-copper alloy is a kind of false alloy with two phase structure mainly composed of tungsten and copper elements. It is a metal matrix composite material. Because of the large difference in the physical properties of copper and tungsten, this alloy can not be produced by melting and casting, and is generally produced by powder alloy technology.

Tungsten-copper alloy is tungsten and copper alloy, commonly used alloy copper content is 10%-50%, alloy with powder metallurgy method, it has a wide range of uses, one of the most used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries, Secondly, it is also used to manufacture high voltage electric switch contact and rocket nozzle throat liner, tail rudder and other high temperature components, also used for electrical processing electrodes, high temperature mold and other requirements of conductive, thermal conductivity and high temperature use occasions.
