With the increasing awareness of environmental protection and the rapid development of the new energy vehicle market, the application of lightweight and high-performance materials in auto parts has become particularly important. As a kind of lightweight and high-strength material, magnesium alloy forging has a wide application prospect in the field of new energy vehicles. This paper will discuss the application and challenges of magnesium alloy forgings in the field of new energy vehicles.
Application of magnesium alloy forgings in new energy vehicle field
Body structure parts: magnesium alloy forgings can be used to manufacture body structure parts of new energy vehicles, such as frames, doors, roofs, etc. Compared with traditional steel, magnesium alloy forgings have lower density, which can significantly reduce the weight of the vehicle and improve the fuel economy and driving performance of the vehicle.
Engine parts: Magnesium alloy forgings can also be used to manufacture engine parts for new energy vehicles, such as crankshaft, connecting rod, cylinder block, etc. Because of its good casting performance and mechanical properties, magnesium alloy can meet the high temperature and high pressure working environment of the engine, reduce the weight of the engine and improve the fuel economy.
Energy storage system components: The energy storage system of new energy vehicles is one of its core components, and magnesium alloy forgings can be used to manufacture the shell, bracket and other components of the energy storage system. Magnesium alloy has good electrical conductivity and corrosion resistance, which can provide effective protection and support to ensure the safe and reliable operation of the energy storage system.
Challenges facing magnesium alloy forgings in the field of new energy vehicles
Cost: At present, the production cost of magnesium alloy forgings is relatively high, mainly due to raw material costs, processing costs and surface treatment costs and other factors. Reducing the cost is the key to realize the wide application of magnesium alloy forgings in the field of new energy vehicles.
Corrosion resistance: Although the corrosion resistance of magnesium alloy forgings can be improved through alloy composition adjustment and surface treatment, it is still necessary to further improve its corrosion resistance in complex and harsh automotive working environments to ensure long-term reliability and safety.
Standardization and large-scale production: At present, the application of magnesium alloy forgings in the field of new energy vehicles has not yet formed a perfect standard and large-scale production system. It is of great significance to promote the wide application of magnesium alloy forgings to promote standardized production and establish a perfect supply chain system.
With the progress of science and technology and the development of industry, the application prospect of magnesium alloy forgings in the field of new energy vehicles will be broader. In the future, it is necessary to strengthen industry-university-research cooperation, increase research and development efforts, reduce costs, improve performance, and promote the large-scale production and application of magnesium alloy forgings. At the same time, a perfect standard and testing system will be established to ensure the quality and reliability of magnesium alloy forgings, and contribute to the sustainable development of the new energy automobile industry.
