body-in-white and automotive aluminum sheet for sale

In addition to body panels, more and more luxury brands have begun to reduce the weight of the car as much as possible by using automotive aluminum alloys to replace the original steel on the body-in-white. For example, after the fourth-generation Land Rover Range Rover uses an all-aluminum body and a large number of aluminum alloy coverings, it is 420 kilograms lighter than the third-generation Range Rover using a steel body, which is equivalent to the reduction of five 170-pound adult men!

Of course, since the cost of the all-aluminum body body-in-white is too high, most luxury cars only use the method of increasing the proportion of aluminum alloy in the body-in-white to reduce weight. For example, Cadillac CT6, by increasing the proportion of aluminum alloy on the body-in-white to 64%, and using various aluminum alloy covering parts, greatly reduced the weight of the whole car, and finally helped the car to be 5 meters 2 long and the size of the standard axle Mercedes-Benz A full-size sedan the same size as the S-Class controls the curb weight at 1663kg, which is about 100kg lighter than the domestic long-axle Mercedes-Benz E-Class that is one size smaller!

When it comes to the models that most need to reduce weight through aluminum alloys, it is undoubtedly the electric vehicles that are gradually becoming mainstream. This is because for every 10% of an electric vehicle's weight, the vehicle's power consumption increases by 5.5%. Let's take an electric vehicle with an aluminum alloy body, a curb weight of 1800kg and a cruising range of 500km as an example. Since the steel body is usually 200kg heavier than the aluminum alloy body and body-in-white, if the body of this electric car is replaced with steel, its weight will reach 2000kg. Correspondingly, the cruising range will be reduced from the original 500km to 472.5km. At this time, if the steel body electric car wants to make up for the lost battery life by increasing the battery capacity, then the car needs to increase the battery capacity of 4.5Kw h to achieve 500km of battery life again, which is equivalent to the need for battery life. It costs about 6000 yuan more.
