Aluminum for Car Plates Grades and Specification

Application of Aluminum Alloy in Automobile:

With the increasing social demand for energy saving and consumption reduction, automobile lightweighting is the current development direction of the automobile industry.

Nowdays, Aluminum alloy has become an ideal lightweight material, and can be controlled by adding different alloy and proportion, as well as the manufacturing process, corresponding applied in the body, chassis and engine cylinder block, cylinder head, piston, intake manifold, rocker arm, engine mount bracket, clutch shell, brake parts, clutch shell and cover shell,etc, effectively reduce the overall weight of the vehicle, thereby improving overall performance.

Advantages of Aluminum for Car Plates :

Aluminum for car plates has many advantages such as light weight, high strength, good stretchability, high corrosion resistance, etc., and it is favored by the automotive and automotive parts processing industries.

Application of Aluminum for Car Plates in Various Parts of Automobile:

The following is the grades and specification of aluminum plates corresponding to each part of the car.

In general, The use of aluminum for car plates focuses on three aspects: car wheels, car engine gearbox shells, and car frames. Of course, there are some such as interior, floor and so on. For automobile body, commonly used aluminum alloy materials mainly include 5000 series 、6000 series alloy plates, profiles, pipes, and high-performance cast aluminum. For different stress parts, different grades of aluminum alloy materials are used..

1. Automobile chassis, using 5000 series or 6000 series alloy materials.
2. As for car frame that the most stressed part of the car body, adopt 2000 series or 7000 series alloy materials, which can be strengthened by heat treatment.
3. Car seats adopt 2000 series or 6000 alloy series materials, which can be strengthened by heat treatment.
4. The skin that the secondary stress part of the car body, are made of 5000 series or 6000 alloy series materials.
5. And the door is made of 5000 series or 6000 series materials.
6. Car wheels, using 6061 aluminum plate.

2 Series Aluminum for Car Plates:

The 2000 series alloy is an aluminum alloy that can be strengthened by heat treatment. It has excellent forgeability, high strength and good welding performance. 2 series alloy also has a good baking strengthening effect, but its corrosion resistance is worse than other series of aluminum alloys. At present, 2036 and 2022 aluminum alloys have been partially used in car body frameworks.

5 Series Aluminum for Car Plates:

The 5000 series alloy is an aluminum alloy that can’t be strengthened by heat treatment. It has good corrosion resistance and welding performance. However, when the machining deformation is carried out in the annealing state, the luders line and the delayed yield may be produced. Therefore, the 5-series alloy is mainly used for the complex shape parts such as the body inner plate. For example, 5083 aluminum plate, 5754 aluminum plate mostly used for the top plate and the bottom guard plate, and the door, front and rear cover of the car, fender and lifter use 5182 aluminum plate.

6 Series Aluminum for Car Plates:

6000 series alloys are heat-treated and strengthenable aluminum alloys, with high strength, good plasticity and excellent corrosion resistance. Compared with the steel plate, the yield strength and tensile strength are similar to 6000 series 2T4 state sheet, and the hardening coefficient even exceeds the steel sheet. Currently, 6009, 6010, and 6016 aluminum alloys are used for outer and inner panels of automobile bodies, because of their good plasticity, and the ability to achieve artificial aging and high strength during the paint baking process after forming. For example, the body panels of the Audi A8 use this series of aluminum alloys. As for aluminum wheels are also mostly used aluminum for car plates 6061. In addition, in order to enhance the cushioning capacity and fatigue resistance of automobiles, Mingtai Al. have developed high-performance aluminum for car plates based on those series of alloy. Nowdays, 6000 series aluminum alloys are the main body panels material.
