Under the global situation of promoting energy conservation and environmental protection, the application of lightweight technology in the automotive industry has been put on the agenda. The application of aluminum alloy sheets for automotive panels is a simple and effective lightweight method. Automotive aluminum panels are among the high-end aluminum alloys. One, due to its stringent requirements on the use properties (forming, joining, etc.) and surface quality, also puts more precise control and management requirements on the processing of raw materials.
The production process of automobile aluminum plate: aluminum liquid is continuously cast into aluminum blank of different specifications, after surface treatment, heating, hot rolling, coiling, cold rolling forming to obtain the required thickness, followed by continuous annealing heat treatment to obtain the desired Microscopic fine organization and performance. There are many key technologies and difficulties in the production of automotive aluminum sheet materials, which will also have an important impact on subsequent performance (stamping, painting, etc.).
Throughout the production process of automotive aluminum panels, the most important are cleanliness (chemical metallurgical process) and uniformity (physical metallurgical process). Reflected in the actual large production process is the control process of smelting (casting) and rolling (heat treatment). Excellent aluminum cleanliness and uniformity of texture (texture) have a positive effect on the stamping and joining properties of subsequent automobile manufacturers.
The chassis of the car occupies a large part of the overall weight of the car. How to effectively reduce the weight of the car body while ensuring safety. The material of the car chassis has high performance requirements for the aluminum plate. The 6061 aluminum plate made of the car chassis has a good experience.
Aluminum plate 6061 is a heat-treated reinforced alloy with good formability, weldability, machinability, moderate strength, and good operability after annealing. It is commonly used in trucks, ships, and tower buildings. And other fields. It is used in the manufacture of automobile chassis to effectively reduce the weight of the car, achieve the purpose of weight reduction, and can ensure the stability of the car, increase the stability, and achieve the effect of damping.
Automotive lightweight has the following advantages: 1. Lightweight. All aluminum is at least 100kg lighter than conventional steel. Improve power, fuel economy, and control. 2. Corrosion resistance. The durability of use is higher than that of steel. 3. More secure. Aluminum absorbs twice as much energy as ordinary steel.
The function of the chassis is to support and install the automobile engine and its various components and assemblies to form the overall shape of the car, and to receive the power of the engine to make the car move and ensure normal driving. At the same time, a good chassis can guarantee the safety of the driver's life.
