Aluminum in Car Interior

 5000 aluminum, known as aluminum-magnesium alloy, is usually used for car interior covering parts, such as doors, roofs, floors, etc. This type of alloy has good formability and corrosion resistance, and is suitable for decorative and structural parts inside the car body.

Due to the moderate strength of 5 series aluminum, it is usually not used for external covering parts that are subject to greater impact. The commonly used alloys are 5182 and astm b209 alloy 5052.

6000 aluminum-magnesium-silicon alloy is more used in automobile exterior coverings, such as hoods, trunk lids, fenders, etc. This type of alloy has high strength and good corrosion resistance, and can withstand the erosion of the external environment and the impact of vehicle driving. 6 series aluminum also has good deformability and is suitable for the manufacture of complex-shaped covering parts.

Composition differences between 5xxx and 6xxx aluminum alloys

5-series aluminum mainly uses magnesium as the main alloying element, and the magnesium content is between 3-5%, so it is also called aluminum-magnesium alloy. It cannot be strengthened by heat treatment, and its mechanical strength is usually improved by work hardening.

6-series aluminum uses magnesium and silicon as the main alloying elements, among which the ratio of magnesium to silicon determines its performance characteristics. The main strengthening phase is Mg2Si, which can be strengthened by heat treatment.

Performance differences between 5xxx and 6xxx

5xxx aluminum is characterized by low density, high tensile strength and high elongation. Therefore, under the same area, the weight of 5-series aluminum is lower than that of other series. It is suitable for applications that require high strength and corrosion resistance, such as ships and automotive parts.

6xxx aluminum has medium strength, good plasticity and excellent corrosion resistance, especially no tendency to stress corrosion cracking. It has excellent weldability, corrosion resistance and cold working properties, and is suitable for applications that require processing and welding, such as construction and aerospace.

Common defects of 5 series and 6 series aluminum

Common defects of 5-series aluminum include delayed yield and stretcher-strain mark. Orange peel effect is easy to appear when the aluminum plate is formed. Increasing the Mg content can inhibit the formation of the stretcher-strain mark to a certain extent, but with the increase of Mg content, the tensile properties decrease significantly and the work hardening phenomenon is serious.
Common defects of 6 series aluminum include cracks and fractures that may occur under certain conditions, especially when subjected to impact or excessive stress.
