Magnesium alloy forgings can be said to be pioneers in the aircraft and automotive industry, with the following advantages: Light weight and high strength: Magnesium alloy has a low density and excellent strength characteristics, making it an ideal material choice in the aviation and automotive industry. Compared to other common structural materials such as steel or aluminum alloys, magnesium alloys have a lower weight and higher specific strength. The use of magnesium forgings in aircraft and automotive manufacturing can significantly reduce overall weight, improve fuel efficiency, increase carrying capacity, and improve vehicle handling and power performance. Excellent corrosion resistance: Magnesium alloys have good corrosion resistance, which is critical for applications such as aircraft and automobiles that are exposed to harsh environments over a long period of time. In aircraft structures, for example, magnesium forgings are resistant to corrosion and temperature extremes at high altitudes, extending service life and improving safety. In the automotive industry, because the vehicle is exposed to different climatic conditions for a long time, the corrosion resistance of magnesium alloy forgings can improve the corrosion resistance of the body and delay the aging and damage of parts. Vibration and noise reduction characteristics: Magnesium alloy forgings have excellent vibration and noise reduction performance, which is particularly important for the aircraft and automotive industry. In the field of aircraft, the use of magnesium alloy forgings can effectively absorb and reduce vibration, reduce flight noise, and improve passenger comfort and safety. In the automotive industry, due to the vibration reduction characteristics of magnesium alloy forgings, the noise and vibration of the vehicle can be reduced while driving, and the ride experience and driving comfort of the car can be improved. In summary, magnesium alloy forgings have advanced advantages in the aircraft and automotive industries such as light weight, high strength, corrosion resistance and vibration and noise reduction characteristics, and can be called one of the pioneer materials in these industries. Through the application of magnesium alloy forgings, weight reduction, fuel efficiency, structural safety and durability can be achieved, thus promoting the development of aircraft and automotive technology.
