Aluminum for automobiles is divided into two series: one is the body structure, which accounts for 70% of the automotive aluminum amount. The car panel thickness is 0.8-4.0 mm and its maximum width is of 2000m. The other is for doors, engine hoods and trunk lids, etc., with a thickness of 0.6-2.0 mm and a maximum width of 1900mm.
Al6061 t6 reaches medium strength, which can be used for automobile fender, hood outer panel and car doors. 6061-O aluminum sheet has good extrusion formability, and the finished product has high hardness after quenching, which can be used for aluminum alloy wheels.
One of the main properties of 6016 aluminum sheet is its formability. In the automotive manufacturing process, 6016 aluminum sheet is often processed into parts of various shapes and sizes. For example, it can be processed into body covers, chassis supports and connectors, etc. Due to its excellent processing properties, operations such as cutting, bending, stamping and welding can be easily performed, which improves production efficiency and quality.
6014 aluminum sheet has excellent strength and durability while still being very lightweight. This makes it ideal for the aerospace and automotive industries. One of the main benefits of 6014 aluminum sheet is its high strength-to-weight ratio.
It has excellent strength while still being much lighter than other metals like steel or titanium. This means manufacturers can use less material without sacrificing performance, saving costs and increasing fuel efficiency.
6111 aluminium is an automotive aluminum alloy that combines high strength, good formability and excellent corrosion resistance. It belongs to the 6xxx series aluminum alloy and is a deformable alloy that can be extruded, rolled or forged into various shapes. 6111 aluminum alloy has excellent energy absorption properties, making it suitable for applications such as automotive collision structures, which can help absorb impact energy during a collision.
Among the registered 6000 series automobile body sheet alloys, 6111 alloy has the highest strength, but its stamping formability is still somewhat inferior to that of deep drawing steel sheets and needs to be further improved. The stamping formability of aluminum alloy sheets is closely related to the texture configuration formed during its production process.
During the entire production and processing of aluminum alloy sheets, there are many factors that affect the final texture configuration of the aluminum sheet, and cold rolling is one of the important factors.
