Today, the term “lightweight” has evolved from the terminology of the automotive industry to the high-frequency vocabulary in media news. In “Made in China 2025”, light weight has also been regarded as an important direction for the development of the automobile industry. To put it simply, light-weighting is to reduce the weight of the vehicle as much as possible while ensuring the strength and safety of the vehicle, thereby improving the vehicle’s power, reducing fuel consumption and reducing exhaust pollution. In recent years, as environmental protection and energy conservation requirements have become stricter, automobile lightweighting has become an unstoppable trend in the development of the world’s automobiles. According to the European Aluminum Association, every 100kg of car quality can save 0.6L of fuel per 100 kilometers and reduce CO2800-900g. Aluminum has a density of only 1\/3 of steel and has good plasticity and recovery. It is an ideal lightweight material for automobiles. During the first oil crisis of the 1970s, in the face of rising oil prices, automakers around the world tried to use aluminum alloys to make steel radiators, cylinder heads and bumpers. Fuel efficiency. Since then, the proportion of aluminum alloys in automobiles has been increasing. According to research data released by the famous consulting firm Ducker Worldwide, the average aluminum consumption in European cars has tripled since 1990, from 50kg to the current 151kg, and will increase to 196kg in 2025.<\/div>\n

At present, the trend of lightweight vehicles is becoming more and more fierce, and aluminum alloys are widely used in hubs, engines, radiators, and oil pipes. The body quality accounts for about 40% of the total mass of the car. For the weight reduction of the whole car, the weight of the car body plays an important role. According to the 2016 European Body Conference (EuroCarBody 2016), the application rate of aluminum alloy has reached more than half of the quality of some high-end models of body-in-white (that is, the body that is welded but not painted). For example, Aston Martin’s DB11 aluminum alloy application rate is as high as 86.1%, the second generation Honda NSX (Acura NSX) is 79.0%, and the 5th generation Land Rover Discovery is 62.9%. However, the application of aluminum alloys on the body of ordinary models is still relatively small. According to data from the well-known consulting firm Ducker Worldwide, the penetration of aluminum alloy panels in car bodies was only 4% in 2015. Today, all-aluminum bodywork is still a technology at the tip of the pyramid, and it is only used on some high-end models. Lightweight body is an important research topic in the development of lightweight manufacturers.<\/div>\n

The automotive deformed aluminum alloy mainly includes a 5xxx series (Al-Mg type), a 6xxx type (Al-Mg-Si type), and a small amount of 2xxx series (Al-Cg type) and 7xxx type (Al-Zn-Mg type). Among them, the 5xxx series alloy can not be heat-treated and strengthened, and the molding property is excellent. However, after forming, the yield point is prolonged and the surface is wrinkled, which affects the appearance quality of the product, and therefore is mainly used for a complicated shape such as an inner panel. The 6xxx series alloy can be heat-treated and strengthened by the solid solution of Mg and Si and the aging precipitation of Mg2Si phase. The strength after coating and drying is improved, and the dent resistance is high, which is suitable for the requirements of outer panel and body frame. Strength, rigidity. Except for rolled sheet, extruded profiles are also important automotive deformed aluminum alloys, generally suitable for structural parts of equal section, such as bumper, energy absorbing box, front section of front longitudinal beam, sill, rear section of rear longitudinal beam. The medium strength 6xxx is the main material for extruded profiles due to its high extrusion rate and surface quality, as well as age hardening properties during extrusion. High-strength 7xxx aluminum alloys are also used to produce extruded profiles where high strength is required. At the same time, in order to improve the impact strength, the profiles of the profiles are mostly “mouth”, “day” and “mesh”.<\/div>\n

Aluminum alloys play an important role in the car lightweight wave, but they also face important challenges. In fact, lightweighting is not just about reducing weight, but about balancing the performance, safety, cost, and weight of the vehicle. At present, the core resistance of automotive aluminum alloys is still high cost, which makes the application of all-aluminum body only limited to high-end models and temporarily unable to expand to a large number of economic models. The performance limitation of aluminum alloys is also an important factor that restricts its development. On some parts, it still cannot replace steel. At the same time, the connection technology of aluminum alloys, especially the multi-material joining technology of cast iron-aluminum, steel-aluminum, magnesium-aluminum, etc., is also a major factor in the application of aluminum alloys in automobiles. Audi’s new A8 D5 \u201cdiscarded\u201d the all-aluminum body that has been in use for more than 20 years, and used a high-strength steel with considerable weight. Affected by this, the D5 model gained 51KG more than the previous model, but the body’s torsional rigidity has increased by 24%, the safety has been greatly enhanced, and the cost has been greatly reduced.<\/div>\n
