大規(guī)格高性能鋁卷帶通常指表面質(zhì)量、尺寸精度、版型以及性能方面要求達到較高標準的鋁精深加工產(chǎn)品，廣泛應(yīng)用于交通運輸（地鐵、高鐵等）、航空航天、海洋船舶、包裝等國民經(jīng)濟發(fā)展和國防建設(shè)領(lǐng)域所需關(guān)鍵基礎(chǔ)材料。
Large size and high-performance aluminum coils usually refer to aluminum precision and deep-processing products that meet high standards in surface quality, dimensional accuracy, version and performance. They are widely used in key basic materials required for national economic development and national defense construction, such as transportation (subway, high-speed railway, etc.), aerospace, marine ships, packaging and so on.
一汽車輕量化：
I. automobile lightweight:
鋁合金被廣泛使用到汽車各部位，如儀表臺及發(fā)動機支架、鋁合金車輪、懸掛系統(tǒng)零件、保險杠防撞梁、汽缸、車門及熱交換器等。鋁代替鋼制造汽車，可將發(fā)動機、車輪均減重約30%，鋁質(zhì)散熱器（與銅制品相比）減重20%~40%，整車重量減輕30%~40%。這大幅度提升了汽車的速度和操控能力。
Aluminum alloy is widely used in various parts of automobile, such as instrument panel and engine support, aluminum alloy wheels, suspension system parts, bumper anti-collision beam, cylinder, door and heat exchanger. Aluminum instead of steel can reduce the weight of engine and wheel by about 30%, aluminum radiator (compared with copper products) by 20% ~ 40%, and the weight of the whole vehicle by 30% ~ 40%. This greatly improves the speed and handling ability of the car.

二高鐵車體材料：
II. High speed railway body materials:
高鐵是“用鋁大戶”，一列高鐵車體材料的85%以上為擠壓鋁型材，整個車體由型材、板材，鑄件與鍛件焊接而成。高鐵車廂不僅對剛性強度有高要求，也對車廂自重有限制條件。鋁合金的密度只占鋼材密度的1/3，但在添加一定元素形成合金后，強度卻比鋼合金更高，自然是選擇！
High speed railway is a "large aluminum user". More than 85% of the materials of a train of high-speed railway car body are extruded aluminum profiles. The whole car body is welded by profiles, plates, castings and forgings. The high-speed railway carriage not only has high requirements for rigid strength, but also has restrictions on the self weight of the carriage. The density of aluminum alloy only accounts for 1 / 3 of the density of steel, but after adding certain elements to form alloy, the strength is higher than that of steel alloy. Naturally, it is a choice!
業(yè)內(nèi)專家還指出，時速300公里以上的高速列車必 須使用鋁合金材質(zhì)，350公里以上的列車車廂除底盤外全部使用鋁型材。
Industry experts also pointed out that high-speed trains with a speed of more than 300 kilometers per hour must use aluminum alloy, and all train carriages with a speed of more than 350 kilometers use aluminum profiles except the chassis.

在同樣強度水平下，鋁合金可提供截面更厚的材料，受壓時的抗屈曲能力更佳，成為經(jīng)典的飛機結(jié)構(gòu)材料。比如高強鋁合金厚板作為主要承力構(gòu)件，使用比例占飛機上總鋁材用量的30%~35%。
At the same strength level, aluminum alloy can provide materials with thicker section and better buckling resistance under compression. It has become a classic aircraft structural material. For example, high-strength aluminum alloy thick plate, as the main load-bearing component, accounts for 30% ~ 35% of the total aluminum consumption on the aircraft.
