Ang mga bagong sasakyan ng enerhiya ay nakakatulong sa pagkamit ng pag save ng enerhiya at pagbawas ng emisyon at pag alis ng presyon ng kapaligiran. Ngunit sa kasalukuyan, ang baterya na ginagamit sa mga bagong sasakyan ng enerhiya ay hindi maaaring matugunan ang mga kinakailangan sa hanay ng sasakyan, lamang upang mabawasan ang bigat ng sasakyan upang mapabuti ang saklaw. 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. Ang density ng aluminyo ay maliit, lamang ang 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, kaagnaan pagtutol, good processing performance and high recycling rate, it makes the amount of aluminum in the automobile grow rapidly.
Sa kasalukuyan, the aluminum alloys used for automotive lightweighting are 5182, 5083, 5754, 5052, 6061 haluang metal aluminyo sheet, atbp. 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, mataas na kaagnasan pagtutol at magandang weldability, and has good application in the field of car chassis protection parts, car doors, wheels and seats.
