Tungsten alloy still have important applications in cutting-edge science such as rockets, missiles, recoverable spacecraft and nuclear reactors. This is due to the excellent physical, mechanical, corrosion and nuclear properties of tungsten alloys. For example, tungsten alloy at 1900℃, the strength is still 44 kg/mm 2, at such a high temperature, whether steel or heat resistant super alloy are melted into liquid, tungsten is mainly used to make various types of rocket engine throat lining without cooling; The nozzle made of silvered tungsten can withstand the high temperature of more than 3100℃. It is used for a variety of missiles and aircraft. The rocket nozzle made of tungsten fiber composite material can withstand 3500℃ or higher temperature. In the chemical industry, it can be used as corrosion-resistant equipment and components, as lubricants, pigments and catalysts for various reactions.
