Aluminum Alloy Sheets for Automobile Panels
Aluminum Alloy Sheets for Automobile Panels can be rolled with 2xxx series, 5xxx series, 6xxx series and 7xxx series aluminum alloys. Except for 5xxx series aluminum alloys, the other three series are heat-treated and strengthened aluminum alloys. Their strength is in the coating and drying process. It is further improved when baking, 661 aluminum plate, 6009 aluminum plate, 6010 aluminum plate, 7075 aluminum plate, 5083 aluminum plate, 5052 aluminum plate, 2024 aluminum plate, 2A12 aluminum plate, etc. After proper heat treatment, high-strength, high-rigidity aluminum Alloy Sheets for Automobile Panels.


 
1. Good formability. The forming process of the car body and the covering sheet metal parts is formed by stamping. The aluminum alloy sheet should have good stamping formability, that is, it has a low yield ratio and high forming limit. It has a variety of stress states of stamping deformation. Very high forming space.
 
2. Strong surface smoothness. The aluminum Alloy Sheets for Automobile Panels must have good flanging ductility and consistent surface color performance after forming, that is, the surface of the formed sheet metal does not appear on the surface of the flat line, that is, the slip line, which is caused by uneven grain or uneven distribution of inclusions The resulting deformation of the surface of the board is uneven, which causes the surface to appear inconsistent in luster after painting.
 
3. Good solderability. The good weldability can meet the requirements of connecting automobile components for welding after forming. The sheet should have anti-aging stability to ensure that there is no aging from the sheet leaving the factory to the stamping production, and to prevent the yield point of the material from rising during the stamping process, resulting in uneven surface deformation and wrinkles, thereby affecting the surface of the automobile outer panel quality.
 
4. Excellent bake hardenability. The lightweight of the automobile also requires the sheet to have high bake hardening, that is, the yield strength of the sheet is significantly increased after the stamping deformation and paint baking, so as to ensure that the sheet metal parts after stamping and painting have high dent resistance. Compatibility between the paint baking process of alloy plates and the current paint baking process of steel plate stamping parts.
 
The use of aluminum is very extensive. Just like the above-mentioned Aluminum Alloy Sheets for Automobile Panels, it is just one of the many ways to use aluminum. Aluminum itself has very good performance and is used as Aluminum Alloy Sheets for Automobile Panels. It also has more performance, which can meet the use of many occasions.
