Nowe pojazdy energetyczne są pomocne w osiąganiu oszczędności energii i redukcji emisji oraz łagodzeniu presji na środowisko. Ale obecnie, akumulator stosowany w pojazdach nowych źródeł energii nie może spełniać wymagań dotyczących zasięgu pojazdu, jedynie po to, aby zmniejszyć masę pojazdu i poprawić zasięg. The relevant research shows that the weight of pure electric vehicles can be reduced by 10kg and the range can be increased by 2.5km, which shows the importance of lightweighting.
The development of automotive lightweighting is inseparable from the choice of vehicle materials. Among many lightweight materials, aluminum alloy material has obvious advantages. Gęstość aluminium jest niewielka, tylko 1/3 of steel. Replacing steel with aluminum alloy material can realize structural optimization and make the body reduce weight by more than 50%. Because aluminum alloy has the advantages of high strength, odporność na korozję, good processing performance and high recycling rate, it makes the amount of aluminum in the automobile grow rapidly.
Obecnie, the aluminum alloys used for automotive lightweighting are 5182, 5083, 5754, 5052, 6061 blacha ze stopu aluminium, itp. They are used in different parts of vehicles. 6061 aluminum sheet is a common alloy for automotive wheels as well as new energy vehicle battery base plates. We can process 6061 aluminum sheet with thickness 0.30-600mm and width 150-2600mm, which has medium strength, wysoka odporność na korozję i dobra spawalność, and has good application in the field of car chassis protection parts, car doors, wheels and seats.
