The performance of aluminum plate for auto
1.Good formability is required pinholes and corrosion marks;
formability of sheet metal refers to its ability to withstand shape changes in the stamping process.Formability can be evaluated by a formability test. At present, there are a large number of test results on the formability of steel plates, but the formability test results of aluminum alloy plates can fully meet the needs of automobile performance.
2. Certain aging stability
The property that aluminum alloy sheets do not age when stored at room temperature is called aging stability. Because aging will make the alloy elongation at the yield point during tensile deformation, that is, Lude ribbon, resulting in uneven surface deformation and wrinkling during stamping, affecting the appearance of stamping parts; Plates often need to be transported and stored for some time from production to parts stamping. Generally, plates are required to be stored at room temperature for 6 months without aging.
3. Good bake hardenability
After stamping, automotive stamping parts will also produce aging when they are baked with paint, which will increase their yield strength, which is called bake hardening. High bake hardenability will give parts high dent resistance. Mingtai Aluminum hopes that the baking hardenability of aluminum alloy plate is the best and compatible with the painting process of steel plates because most car enterprises currently design the paint baking process for steel plates, and the baking hardenability of aluminum alloy plates is obviously different from that of steel; The bake hardenability of the material can be evaluated according to relevant standards.
4. Good flanging ductility
When stamping flanging of automobile outer panel, the cracking resistance of plate is called flanging ductility. Therefore, an aluminum alloy plate is required to have good flanging ductility to ensure no cracking during flanging. The flanging ductility of the plate is related to the total elongation of the plate and the internal structure of the material. The flanging ductility can be tested by cold bending test, but the sensitivity of strain rate is not considered in general cold bending, while the deformation is fast and the strain rate is large during stamping flanging, so there are higher requirements for flanging ductility.
5. Good surface freshness
An aluminum alloy plate is different from a steel plate, and its grain size is much larger than that of steel. Under the coarser grain, if the grain size is uneven, it will lead to uneven deformation like rope grommet on the surface of stamping parts along the rolling direction. This surface defect is also called Luo Ping line, resulting in inconsistent surface gloss after painting. Therefore, aluminum alloy plate for automobile needs to have better surface gloss.
6. Surface treatment and coating performance
Before painting, the surface of iron and steel materials should be pickled and Phosphated to improve the adhesion between the surface of stamping parts and paint and improve their corrosion resistance; Because there will be a closely bonded oxide film on the surface of aluminum alloy, the surface treatment method before painting is different from that of iron and steel materials. Instead of using the general acid phosphating method, chromium treatment is adopted. Considering the toxicity of hexavalent chromium to the human body, chromium-free or low chromium treatment technology has been developed in recent years, which can meet the needs of enterprises.
