As far as the whole automobile industry is concerned, the consumption of aluminum in body parts will continue to increase, which is mainly driven by electric vehicles. The former pays attention to lightweight strategy, either extends the mileage while retaining the same battery, or uses a smaller battery, while the application of
sheet metal for automotive parts is just conducive to automobile lightweight design.
Sheet metal for automotive parts has the characteristics of small density, corrosion resistance and so on. Now it is widely used in automobile parts.
Sheet metal for automotive parts greatly reduces the self weight of the car, reduces fuel consumption, and responds to the call of the national environmental protection department for energy conservation and emission reduction. Therefore, it also becomes the key to improve the competition of major automobile manufacturers. The common
sheet metal for automotive parts are 3104 aluminum plate, 3105 aluminum plate, 3003 aluminum plate and other alloy brands. Aluminum has good oxidation resistance, forms a compact oxide film on the surface of aluminum, and well prevents the chemical reaction with external substances, and has good corrosion resistance. Therefore, it also ensures the service life of the car. It can be said that aluminum alloy is a star metal in the current metal industry, which has wide application and strong practicability. 3003 aluminum plate, 3104 aluminum plate and 3105 aluminum plate alloy are used for fuel tank and auto parts.
Sheet metal for automotive parts can be rolled with 2XXX series, 5xxx series, 6xxx series and 7xxx series aluminum alloy. Except for the 5xxx series aluminum alloy, the other three series are heat-treated and can strengthen the aluminum alloy. Their strength is further improved when coating and baking. The 661 aluminum plate, 6009 aluminum plate, 6010 aluminum plate, 7075 aluminum plate, 5083 aluminum plate, 5052 aluminum plate, 2024 aluminum plate, 2A12 aluminum plate, etc. are all suitable for rolling After the heat treatment, high strength and high rigidity aluminum plate for automobile can be obtained.
