Tungsten-based Alloys in The Construction of National Defense and The Important Role of the National Economy

In the aerospace industry applications. China developed the first generation of tungsten heavy alloy performance good in the 1960s, since immediately after the birth of self-developed China's first artificial satellite navigation device has been successfully applied, then this new material has the first in China an intercontinental missile and developed by a variety of new fighters, helicopters, has been successfully applied. Developed to meet the needs of Chinese communications satellite, but also successfully developed a new type of density up to 18.5g/cm3 high proportion of tungsten-based alloys. A variety of high-performance W-Cu alloys in the rocket (missile) combustion chamber, nozzle, throat, rudder and other parts of the development of high temperature has been applied.

Military industrial applications. China has successful developed the W-Ni-Fe heavy alloy, provides of a variety of wear, shaped charge of the development a key material. W-Ni-Cu heavy alloys also play an important role in doing gyrorotor high proportion of material in China's first nuclear submarine of the research and development.

In the civilian industry and nuclear industrial applications. In the nuclear power industry, used for nuclear reactor insulation and shielding materials, tungsten heavy alloy has a good prospect. In civilian industry, high-density tungsten alloy has been more widely used; mobile phones and golf oscillator rod weight will be a wide range of products. Processing done in the electric performance of the anvil block material to make electrical upsetting of hundredfold increase production efficiency, has significant economic benefits.

In summary, the development of tungsten processing industry does not only play a very important role in building on the national economy, also has a significant impact on the modernization of national defense.
