How is the application prospect of tungsten heavy alloy in aero engine field?

High specific gravity Tungsten Alloy is a kind of alloy material with high density, high melting point, high strength and high heat resistance, which is widely used in aero engine field. It has the following advantages, so that it has a broad application prospect in the field of aeroengine.

First of all, Tungsten Heavy alloys have extremely high melting point and density. The melting point of high specific gravity tungsten alloy can be reached about 3410℃, which is much higher than that of other metal materials such as steel and aluminum alloy, which makes it able to work in a high temperature environment and can withstand the high temperature and high pressure working conditions of the engine. At the same time, the density of tungsten alloy is also very high, around 19.3g/cm³, which is nearly twice the density of steel, which makes it able to provide better structural strength and dynamic properties.

Secondly, Tungsten Heavy Alloys has excellent heat resistance. Aeroengine operating temperature is very high,Tungsten Alloys has a low coefficient of thermal expansion and good thermal conductivity, can maintain good mechanical properties at high temperature, not easy to occur thermal deformation and creep phenomenon, to ensure the normal operation of the engine. In addition, high-gravity tungsten alloy has excellent high-temperature corrosion resistance, which can resist high-temperature oxidation, oxidation-corrosion and molten salt erosion and other corrosion forms, extending the service life of aviation engines.

Third, high specific gravity tungsten alloy has excellent mechanical properties. Tungsten alloy has high strength and hardness, can withstand high load and impact force, and has excellent tensile, compressive and bending resistance. Its high toughness and good fatigue life make it widely used in impeller, turbine, nozzle and other parts of aeroengine. In addition, high specific gravity tungsten alloy can also be tempered and improved mechanical properties through heat treatment and processing technology, improve its fatigue resistance and durability.

In addition, high specific gravity tungsten alloy has good radiation damage resistance. The aero-engine works in the high altitude environment and will be affected by radiation. Tungsten alloy with high specific gravity has good resistance to strong radiation and neutron irradiation, which can effectively prevent the damage of radiation and protect the structure and performance of the engine. This makes it have a wide application prospect in the field of aviation, especially in spacecraft and missiles and other high radiation environment.

In addition, high specific gravity tungsten alloy also has excellent corrosion resistance. In the field of aviation, metal materials often need to withstand the erosion and corrosion of air currents, water vapor, oxygen and fuel during high-speed flight. High specific gravity tungsten alloy has excellent corrosion resistance, which can effectively resist the erosion and damage of various corrosive media, and enhance the service life and reliability of aircraft engines.

Tungsten alloy has a broad application prospect in the field of aeroengine. Its advantages of high melting point, high density, heat resistance, mechanical properties, radiation resistance and corrosion resistance make it able to adapt to the high temperature, high pressure, high speed, high load and harsh environment and other working conditions of aircraft engines to ensure the normal operation and safety and reliability of the engine. At the same time, with the continuous development of the aviation industry and the continuous progress of aviation engines, the application prospects of high specific gravity tungsten alloy will also be broader, and make greater contributions to the development of the aviation industry.
