Magnesium alloy forging is an innovative material in the construction industry, which has unique advantages and wide application prospects. First of all, magnesium alloys have extremely high strength and lightweight characteristics. Compared with common construction materials such as steel and aluminum alloy, magnesium alloy has a higher specific strength, that is, it is lighter while maintaining a certain strength. This makes the application of magnesium alloy forgings in the construction field can reduce the structural load, reduce the self-weight load, and improve the overall strength and stability of the building. Secondly, magnesium alloy forgings have good corrosion resistance. The corrosion resistance of magnesium alloy forgings in outdoor environment is better than that of other common metal materials, especially in the harsh environment such as Marine climate and acid rain, its corrosion resistance is more prominent. This makes magnesium alloy forgings suitable for building facades, balconies, stair railings and other parts that need to be exposed for a long time. In addition, magnesium alloy forgings also have good plasticity and formability, and various complex shapes and precision sizes of parts can be manufactured by forging process. This feature enables magnesium alloy forgings to meet the design needs of different parts and requirements in the building, and improve the overall aesthetics and functionality of the building. In short, as an innovative material in the construction industry, magnesium alloy forgings have broad application prospects in building structure, facade decoration, outdoor facilities and other aspects due to their lightweight, high strength and corrosion resistance. With the further development and maturity of technology, it is believed that magnesium alloy forgings will play a more important role in the construction industry.
