The important role of tungsten based alloy in national defense and national economic construction
(1) Application in aerospace industry. The first generation of tungsten based high specific gravity alloys developed in China in the 1960s were developed. Since its birth, it has been successfully used in the navigator of the first man-made satellite developed by China. Subsequently, this new material has been successfully applied in China's first intercontinental missile and various new fighters and helicopters developed by ourselves. In order to meet the requirements of the development of China's communication satellite, a new tungsten based high specific gravity alloy with a density of 18.5 GCM 'has been successfully developed. Avariety of high-performance tungsten alloys (W-Cu alloys) have been used in the development of high-temperature components such as rocket (missile) combustor, nozzle, throat liner and rudder.
(2) Application in military industry. The successful development of tungsten alloys W-Ni-Fe high specific gravity alloy in China provides key materials for the development of various penetrators and penetrators. Tungsten alloys W-Ni-Cu high density alloy as gyro rotor material also plays an important role in the development of China's first nuclear submarine.
(3) Application in nuclear industry and civil industry. In the nuclear energy industry, tungsten based high density alloy has a good application prospect as a heat insulation and radiation protection material for nuclear reactors. Tungsten based high density alloy has been widely used in civil and industrial applications. Mobile phone vibrator and golf club counterweight are products with large quantity and wide range. In electrothermal processing, making anvil block material with excellent performance can improve the production efficiency of electric inlay by hundreds of times, which has significant economic benefits.
