汽车热交换器用三层复合铝箔

摘要

The application and development of 3-layer composite aluminum foil used in automobile heat transfer,including its material construction,performance parameters and manufacturing methods,are introduced.Having the same frame as a sandwich,3-layer composite aluminum foil is made with Al-Mn alloy as its cove material and covered by Al-Si alloy on its two sides,leaving excellent comprehensive performances and 40% weight saving can be obtained compared with these products by copper foil.With the development of sophisticated technology such as hot roll-bonding and cold roll-bending,this product has been widely in automobile field and has good application prospects.%综述三层复合铝箔在汽车热交换器中的应用与发展现状,介绍其材料构造、性能参数和生产工艺.三层复合铝箔是以Al-Si系铝合金为芯材,双面包覆Al-Mn系铝合金而构成,具有优异的综合性能,密度比同类铜箔产品少40%.复合铝箔的热轧及冷轧制备工艺也已相当成熟,在汽车工业中应用广泛,具有很好的市场发展前景.
