Generally speaking, car aluminium is mainly used in three aspects: automobile wheels, automobile engine gearbox and body in white. There are also other uses like interior trim and bottom plate. The common aluminum alloy for automobile body include 2xxx, 5xxx and 6xxx. Different types of aluminum alloy materials are used for different stress parts.
Among the many aluminum alloys, the 5 series and 6 series aluminum alloys have excellent performance in the field of automobile manufacturing, especially 5052 aluminum cut to size. It is a widely used rust-proof aluminum plate with high strength, especially fatigue resistance, high plasticity and corrosion resistance, good weldability,etc.
5052 Aluminum sheet is a kind of aluminum alloy that cannot be strengthened by heat treatment. It is suitable for parts with complex shapes such as the inner panel of the body, and can also be used for automobile skins, doors, automobile engine outer plates, automobile fuel tanks, etc. Why can 5052 aluminum used for cars? Lets have a look of 5052 aluminum properties.
There are various processing methods for aluminum sheets in the process of use, including stretching. Aluminum sheets are stretched and then made into aluminum products and aluminum accessories. 5052 alloy often needs to be stretched during use.
The aluminum sheet must have good flanging ductility and the performance of consistent surface color after forming, that is, there is no roping line on the surface of the formed sheet metal part. It is the uneven surface deformation of the sheet caused by uneven grains or uneven distribution of inclusions, so that the surface appears inconsistent in luster after painting.
It can meet the welding requirements of automotive components after forming. The sheet should have anti-aging stability to ensure that aging does not occur from the factory to the stamping production, and prevent the yield point of the material from rising during stamping, which will induce uneven surface deformation and wrinkling, thereby affecting the surface quality of automobile outer panels. .
The lightweight of automobiles also requires high bake hardenability of the aluminum sheet, that is, the yield strength of the sheet is significantly increased after stamping deformation and paint baking, so as to ensure that the sheet metal parts after stamping and painting have high dent resistance.
