About the application of aluminum alloy profiles in new energy vehicles

Today, the automotive industry is developing rapidly, but energy issues are becoming increasingly urgent, and the environmental problems caused by automobiles are also attracting much attention. The development of the new energy vehicle industry is an effective way to alleviate the energy crisis, reduce greenhouse gas emissions, and reduce environmental pollution. At present, new energy vehicles have become an important direction for the transformation and development of the automotive industry.

??New energy vehicles are different from traditional vehicles. They use batteries as power to drive the car. They are restricted by the weight of the power battery, the mileage of the power battery, and the high pressure of the automobile energy-saving and emission reduction policy. In terms of vehicle design and material application, the lightweight of the body has become the first issue that car companies should consider. Therefore, battery-driven new energy vehicles are more urgently in need of body weight reduction than traditional vehicles. This also opens up a broader market space for lightweight materials such as aluminum.

??Among automotive lightweight materials, the comprehensive cost-effectiveness of aluminum alloy materials is higher than that of steel, magnesium, plastic and composite materials, and has relatively large advantages in terms of application technology, operation safety and recycling. The density of aluminum is only 1/3 of that of steel, and its weight reduction and energy-saving effects are obvious, and it can better improve riding comfort while ensuring safety. At the same time, aluminum is easier to recycle and reuse. The comprehensive cost-effectiveness of aluminum determines that it is the best choice for lightweight automotive applications.

??The main application parts of aluminum in new energy automotive parts are body, wheel hub, chassis, anti-collision beam, power battery, etc. According to the processing form, automotive aluminum is mainly divided into three forms: die casting, extrusion and rolling. Among them, die casting accounts for about 80%, and extrusion and rolling each account for about 10%. Die castings are mainly used in engines, wheels and other parts, extrusions are mainly used for seats, luggage racks, door beams, etc., and rolling parts are mainly used to produce aluminum plates for body, etc.

??Among them, the body includes a body frame made of high-performance aluminum profiles and skins and doors made of high-precision aluminum plates; aluminum alloy wheels (cast aluminum wheels or forged aluminum wheels); the chassis includes high-strength and high-section aluminum profile structural parts and aluminum alloy forgings; in the past, new energy vehicles mostly used steel materials to make electric vehicle power battery trays, but now the application of aluminum alloy materials has gradually surpassed steel. Aluminum alloys have obvious advantages in terms of density, compression and welding.
