The types of materials used in forgings for new energy vehicles include aluminum alloy, magnesium alloy, titanium alloy, high-strength steel, and composite materials. Among them, aluminum alloy forgings have the advantages of light weight, high strength, and corrosion resistance, and are widely used in new energy vehicles.
According to national policies, in order to promote the development of the new energy vehicle industry, achieve energy conservation and emission reduction, and contribute to green development, the Ministry of Industry and Information Technology issued the “New Energy Vehicle Industry Development Plan (2017-2025)”, which outlines the guidance direction and development goals for the development of new energy vehicles and divides the new energy vehicle industry into six areas: pure electric vehicles, plug-in hybrid vehicles, fuel cell vehicles, new energy logistics vehicles, new energy public transportation and special vehicles, and core components. In these fields, various materials play a very important role. Among them, aluminum alloy forgings are widely used. For example, Xiaopeng Motors’ intelligent electric SUV P7 uses a large amount of aluminum alloy material to bring a lighter body weight and higher body rigidity. At the same time, in terms of body strength and safety, aluminum alloy forgings exhibit superior performance.
In addition, in actual production, some forging manufacturers are also constantly researching and developing new materials to meet market demand. For example, Ningbo Catic Casting & Forging Group has developed a composite material that combines polypropylene microbeads with Al-Mg alloy. This material has the characteristics of low density, high strength, and low thermal expansion coefficient, and is suitable for automotive chassis, engine, and transmission system components.
In summary, there are many types of materials for forgings in new energy vehicles, and aluminum alloy forgings are the most widely used. In the future, with the continuous development of technology, more new materials will also be used in the field of new energy vehicles.
