Aluminum car body sheet metal is used extensively for automotive parts as hoods, trunk lids, and doors because of its light weight, workability, and recyclability. and its market share continues to increase.
The 5xxx and 6xxx aluminum alloys are used most commonly for automotive applications. Their mechanical properties for automotive body sheets are listed, and their specific properties and main differences are shown.
The 5xxx alloys have ultimate tensile strength of 125 to 350 MPa and cannot be heat-treated. They have relatively good formability and are highly resistant to corrosion.
However, 5xxx alloys are prone to the formation of Haomei Aluminum during forming, so they are used mostly for inner-panel applications. 5182 and 5754 are the principal 5xxx series alloys used in auto body sheet panels. 5754 also is recommended for elevated temperature applications. The 6xxx series alloys are heattreatable to reach ultimate tensile strength of 125 to 400 MPa. The alloys, especially 6022 and 6111, often are used for outer panels since they are precipitation-hardened and free of Haomei Aluminum.
