In recent years, automobile lightweight has attracted more and more attention, which is of extremely important significance to automobiles. Realize the lightweight of the car, the weight of the whole vehicle can be reduced by 10%, the fuel efficiency can be increased by 6%-8%, and the fuel consumption per 100 kilometers can be reduced by 0.3-0.6 liters.

Aluminum alloy has the advantage of low density, with a density of 2.70 g/cm3, which is much smaller than that of steel; it also has the characteristics of high strength, extremely strong plasticity, and easy processing; and it also has good electrical conductivity, thermal conductivity, and good corrosion resistance. Advantages, excellent application in the automotive lightweight industry.

For the automotive lightweight industry, Shengda Qianliang Aluminum has its own melting and casting workshop, using online degassing and slagging processes, and maturely produced alloy grades: 6005, 6060, 6463, 6082, etc. The extrusion process adopts isothermal and constant velocity extrusion to ensure the consistency of the profile. The tensile strength of 6082 material can reach more than 360MPa.

The lightweight automobile mainly uses 6-series aluminum profiles. Good plasticity and excellent corrosion resistance, especially no stress corrosion, cracking tendency, and good welding performance make the 6 series aluminum profile extremely suitable for the application of this project.
