The vehicle body is the main structure of the vehicle. In addition to creating a passenger cabin and driving compartment, it must also reserve space for mechanical components such as the engine. When we look at the car body from the outside, we see surface coverings, such as front and rear bumpers, engine panels, fenders, door panels and other components. They are of great significance to the overall weight reduction of the vehicle.
At present, the auto body sheet metal mainly includes 5 series and 6 series aluminum alloys. 5 series aluminum alloy has excellent deep stamping properties and is mainly used for body inner panel structural parts.
Although the forming performance of 6 series aluminum alloy is not as good as that of 5 series aluminum alloy, its appearance quality after molding is good and its strength can be improved through baking hardening in the painting stage. It is widely used in interior and exterior covering parts of car bodies.
6111 aluminum and 2008 aluminum alloys are widely used in automobile body outer panels, and 5083 and 5754 are used in inner body panels. Bonnets are made from 2036, 6016 and 6111 alloys. 5456 aluminum is used in truck and trailer body panels.
5754 aluminum alloy is used in the manufacturing of door linings. It has the advantages of high strength, good plasticity, high specific strength, good welding performance, strong temperature resistance, good corrosion resistance, and high fatigue resistance.
The main alloy grades of 6xxx series automotive aluminum sheets include 6016, 6014, 6022, etc., which are currently the main aluminum alloys used in vehicle body exterior panels. Automotive panels have high requirements on comprehensive performance, surface quality and quality stability.
The current mainstream aluminum alloy automotive sheet production process is relatively complex, including several major processes: casting, soaking, machining, hot rolling, cold rolling, and continuous heat treatment.
The thickness of automobile aluminum alloy plates is generally 0.8~1.6mm, and the maximum width is 2300mm. Haomei automotive aluminum sheets are of good formability, low yield-to-strength ratio, high forming limit, strong surface smoothness, good weldability and excellent bake hardenability.
