The production process of automotive aluminium sheets

With the concept of energy saving and environmental protection taking root, the application of lightweight technology in the automotive industry has been pushed onto a new agenda of energy saving and environmental protection. Customer's demand for better quality of cars has led to higher and higher requirements for the manufacturing process of aluminium sheets for car bodies. The application of aluminium alloy sheets for automotive coverings is a simple and effective way to lighten the weight. Aluminium alloys for automotive applications are part of the family of high-end aluminium alloys, which, due to their stringent requirements for serviceability (forming, joining, etc.) and surface quality, also impose finer control management requirements on the processing of raw materials. The production process and performance requirements of aluminium sheets for car bodies are now described in detail by the aluminium sheet generation manufacturers.

We introduce the production process of aluminium sheets for automobiles. Aluminium liquid is continuously cast into aluminium billets of different specifications, which are surface treated, heated and then hot rolled, rolled and cold rolled into shape to obtain the required thickness, followed by continuous annealing heat treatment to obtain the required microscopic fine organisation and properties. There are many key technologies and difficulties in the production of automotive aluminium sheet materials, which will also have an important impact on the subsequent use properties (stamping, painting, etc.). Throughout the production process of automotive aluminium sheets, the microstructure can be simply summarised in two aspects: cleanliness (chemical metallurgical process) and homogeneity (physical metallurgical process). Reflected in the actual production process is the control process for melting (casting) and rolling (heat treatment). Excellent aluminium cleanliness and organisational (weave) homogeneity have a positive effect on the subsequent press forming and joining properties in the automotive production plant.
