automotive aluminum alloy and automotive aluminum plate

Friends who often pay attention to the car circle should have found that aluminum as a body material, its strength is no worse than the engine, gearbox, chassis these three major parts. If any new car uses an aluminum alloy body, the manufacturer not only has to blow several pages of PPT, but also usually pulls the body-in-white to auto shows, 4S stores, and shopping malls to wander around. In addition to manufacturers, consumers' attention to aluminum is also not low, who new cars dare to use less aluminum than the overseas version, netizens will be indignant to raise the keyboard, minute by minute to occupy the forum. So the question is, how much stronger can aluminum be than steel? In addition to lightness, what other unique skills does aluminum have? Why do good cars have a soft spot for aluminum? Please read on!

Compared with the steel used in cheaper models, the biggest advantage of aluminum alloy is that it is light enough! You know, the density of steel is 7.8g/cm³, while the density of aluminum is only 2.7g/cm³. This means that at the same volume, the weight of aluminum is only about one-third of steel, even lighter than the 4.5g/cm³ of the ultra-light titanium alloy. Therefore, the use of aluminum alloy materials on the body, or the replacement of the covering parts on the original steel body, including doors, hood, and fenders, with aluminum, is to reduce weight. In the current domestic market, the BMW 5 Series can be said to be a representative model with aluminum coverings. Here we may wish to make a comparison, and the domestic Mercedes-Benz E-class of the same level as the 5 series because of the cover "aluminum for steel", the curb weight of the lowest model has reached 1780kg, while the same minimum 5 series is only 1705kg, which is equivalent to the E-class naturally pulling a person weighing 150 pounds more than the 5 series!
