With the continuous development of automobile lightweight, many parts of automobiles choose aluminum alloy as the raw material, and 6061 aluminum plate also plays an important role. That is, 6061 aluminum plate can be used as a material for automobile cover parts. Next, the 6061 aluminum plate manufacturer will introduce to you why 6061 aluminum plate is used for automobile cover parts.
Characteristics of 6061 aluminum sheet automotive cover parts: Compared with general stamping parts, 6061 aluminum sheet automotive cover parts have high dimensional accuracy, good shape accuracy, high surface quality, good rigidity, and good processability. 6061 aluminum sheet automotive panels are accurately welded, with an overall design that does not deviate from the body, and a beautiful and elegant appearance. At the same time, they can also withstand certain loads, easily arrange stamping processes and mold design, and obtain high-quality products
6061 aluminum plate has a dense oxide film on its surface, which has long-term corrosion resistance. However, steel does not have this dense oxide film and is very prone to oxidation. The aluminum alloys 5xxx and 6xxx series used in the automotive industry have excellent corrosion resistance. After painting, the 6xxx series alloy may experience filamentous corrosion due to the presence of chloride ions and surface polishing. Lines similar to wheel prints may appear locally on thin or cut edges and expand under the paint film.
The surface pre-treatment of 6xxx series alloy plates is believed to effectively slow down filamentous corrosion. The surface treated with zirconium fluoride exhibits better performance than chromate. And other treatment methods based on zirconium or titanium salts are widely considered more environmentally friendly than using chromates. Compared with rolled surfaces and acid washed surfaces, aluminum alloy sheets treated with surface pretreatment can also improve bonding strength for a long time, giving better adhesion to the adhesive and improving the stability of the primer and coating.
