Tungsten-Nickel-Iron Alloy as High-Temperature Resistant Component Applications

Tungsten-nickel-iron alloy, as a high-temperature resistant component, exhibits excellent performance in high-temperature working environments and is widely used in various industrial fields. In aero-engines, this alloy is often used to manufacture key components such as turbine blades and combustion chamber liners. When an aero-engine is working, the internal temperature can reach thousands of degrees Celsius, accompanied by drastic pressure changes and airflow impact. Tungsten-nickel-iron alloy, with its high melting point and good high-temperature strength, can maintain structural stability in such extreme environments, not easily deformed or melted, ensuring the continuous and efficient operation of the engine. In high-temperature furnaces in the metallurgical industry, the alloy can be used as a high-temperature resistant lining for the furnace bottom and furnace wall, resisting direct burning of high-temperature flames and corrosion of metal melts, prolonging the service life of the furnace and reducing maintenance costs. In the energy field, some core components of nuclear reactors are also made of tungsten-nickel-iron alloy. It can not only withstand the high temperature during reactor operation but also resist radiation damage to the material, ensuring the safe and stable operation of the nuclear reactor. In addition, in components such as nozzles of rocket propulsion systems, the alloy also plays an important role. Facing the high-temperature and high-pressure airflow generated by fuel combustion, it can effectively resist thermal shock, maintain the shape and performance of the nozzle, and ensure the normal launch of the rocket. Its excellent high-temperature resistance and structural stability make it an indispensable key material in high-temperature working environments.
