2025-02-28

Aluminium and aluminium alloys are good lightweight materials for automobiles because of their lighter weight, better machinability and corrosion resistance. The density of aluminium alloy is only 2.68g/cm3, which is only 30% of that of steel. Under the condition of equal bending zone stiffness, the thickness ratio of aluminium to steel is 1.43, and the weight reduction potential of aluminium is 49%, and under the condition of equal bending strength, the weight reduction potential of aluminium to steel is 38%. Statistics show that aluminium alloy replaces traditional steel and copper components, and the weight reduction ratio of body, chassis and heat exchange system can reach 30-40%. The application of aluminium extrusion in China's transportation field only accounts for 27% of the overall demand for industrial aluminium extrusion, far lower than North America (47%), Europe (45%), Japan (50%) and other developed markets, in the energy saving and emission reduction, the development of new energy vehicles and improve the mobility of automobiles under the trend of the trend of automotive lightweight trend.
