In automobile manufacturing, the amount of aluminum alloy used varies depending on the model and manufacturing process. Generally speaking, the body and engine of an ordinary car use about 150-200 kg of aluminum alloy.
For electric vehicles, the amount of aluminum alloy used is more than that of ordinary cars, and its proportion is generally around 30%-40%. This is because electric vehicles need lighter weight to increase the range.
Automobile aluminum alloy has the advantages of lightweight, high strength, and corrosion resistance, which plays an important role in improving automobile performance and reducing fuel consumption.
Where are aluminum alloys mainly used in automobiles?
Car wheels: Nowadays, car wheels are basically made of aluminum. Using aluminum alloy wheels has a very obvious effect on reducing fuel consumption of cars, and most car wheels use 6061 aluminum alloy.
Four doors and two covers of the car: The four doors and two covers of the car are mainly made of 5182 aluminum. Since the 5182 aluminum plate has excellent deformability, it can absorb the impact force well when it is hit by external force, and protect the driver and passengers to a greater extent. Therefore, the four doors and two covers made of 5182 aluminum alloy are safer.
Automobile chassis: The aluminum alloy materials used in this part include 5083 aluminum alloy, 5754 aluminum alloy, 6061 aluminum alloy, etc. Power battery shell and cover plate: This part mainly uses 3003 aluminum plate, and the 3003H14 power battery shell is the main material of its core power battery.
Battery side plate: The battery pack side plate is mainly made of 5083 aluminum plate, which belongs to the AL-Mg alloy. The main alloy element is magnesium, which has high strength, good forming and processing performance, corrosion resistance, and weldability.
Automobile water cooling plate: Brazed composite plate, 3003 aluminum plate. Usually, aluminum brazing plate products are brazed with two pieces of O-state aluminum sheets, one of which is stamped with a flow channel structure to facilitate the circulation of antifreeze for cooling the battery, thereby continuously cooling the battery.
Battery aluminum tray: For battery aluminum trays, due to their light weight and low melting point, there are generally several forms: die-cast aluminum trays, extruded aluminum alloy frames and aluminum plate splicing and welding trays (shells), and molded upper covers.
In the future, aluminum alloys will continue to be widely used. The following are some application trends of aluminum alloys in automobile manufacturing: Body structural parts: The application of aluminum alloys in automobile body structural parts will continue to expand.
Aluminum alloys have the advantages of lightweight, high strength, and corrosion resistance. They can improve the fuel efficiency of vehicles and reduce carbon emissions. At the same time, they can also reduce the overall weight of vehicles and improve the safety and stability of vehicles.
Power system: The application of aluminum alloys in automotive power systems will also continue to increase. Aluminum alloys can be used to manufacture engine cylinder blocks, cylinder heads and other components. They have the advantages of good thermal conductivity and strong corrosion resistance, which can improve the performance and life of engines.
Seats and interior parts: Aluminum alloys can be used to manufacture seats and interior parts, such as dashboards, center consoles, door interior panels, etc.
These parts need to have good strength, stiffness and corrosion resistance, as well as good processing performance and appearance quality. Chassis and anti-collision beams: Aluminum alloys can be used to manufacture components such as chassis and anti-collision beams. These components need to have high strength and stiffness, as well as good corrosion resistance and processing performance.
Suspension system: The application of aluminum alloys in automotive suspension systems will also gradually increase. Aluminum alloys can be used to manufacture suspension components, such as swing arms, spring seats, etc., with the advantages of lightweight, high strength, and corrosion resistance, which can improve the handling and comfort of the vehicle.
New energy vehicles: The application of aluminum alloys in new energy vehicles will also gradually increase. Aluminum alloys can be used to manufacture battery housings, motor housings and other components, with the advantages of lightweight, high strength, and corrosion resistance, which can improve the cruising range and safety of new energy vehicles.
In short, with the continuous development and progress of automobile manufacturing technology, the application of aluminum alloys in automobile manufacturing will continue to increase, playing an important role in improving automobile performance, reducing fuel consumption, and reducing carbon emissions.
