Knowledge collection of alloy aluminum plate used in vehicles

First, the significance of the application of automotive aluminum plate:

With the improvement of energy-saving environmental requirements, automobile lightweight has always been the focus of OEM research. The reduction of vehicle weight can directly improve vehicle fuel efficiency, reduce fuel consumption, improve vehicle handling, and correspondingly improve vehicle safety performance. Alloy aluminum plate has the characteristics of light weight, high strength and good corrosion resistance. Conforming to the general trend of energy-saving environment and improving the performance of the whole vehicle, aluminum plate will be more and more used in the development of automobile parts. Because of its low plasticity and soft material, the aluminum plate will form a kind of collapse protection for pedestrians in the accident of people and vehicles when it is applied to the outer body panel, which will protect the safety of pedestrians to a great extent.

Second, the inspection and repair of aluminum products:

In terms of stiffness characteristics, the stiffness of steel plate stamping parts is much higher than that of aluminum alloy plate stamping parts, and aluminum plate stamping parts are relatively soft. In the process of parts inspection, in order to ensure the overall integrity of alloy aluminum stamping parts, attention should be paid to handling with care. However, aluminum stamping parts require high surface smoothness, and their surface inspection methods are similar to those of rigid stamping parts. Several different methods, such as visual inspection, touch inspection and oilstone inspection, can be applied to the surface inspection of aluminum stamping parts. However, in the process of using touch inspection and oilstone inspection, in order to avoid the damage of inspection method to the surface of stamping parts, the applied pressure needs to be moderate, so as to avoid the deformation of parts caused by using too much pressure. In the process of product inspection, the inspection department can build an excellent grinding sample frame according to the part surface to ensure the quality and efficiency of product inspection. Due to the low rigidity of aluminum alloy sheet stamping workpiece, stamping parts can not be repaired in one piece, and it is impossible to ensure that the parts meet the actual needs in the actual production process. Generally speaking, the defects on the stamping parts can be retained and rebuilt after being combined with the assembly parts.

Third, the prospect analysis of automotive alloy aluminum plate:

With the coming implementation of the National Sixth Emission Standard, carbon emission requirements are becoming more and more stringent, and weight reduction is a big change for automakers. Because of the excellent weight reduction efficiency of aluminum plate (the weight reduction can reach 30% if the same model adopts all-aluminum body), aluminum plate can play a decisive role in the automobile industry in the future.
