Description

一种高性能铝合金空调箔
技术领域
本发明属于冶金领域,具体涉及一种高性能铝合金空调箔。
背景技术
铝由于具有密度小、导热性好、易于加工、无味、环保及价格低廉等优点被广泛使用,用铝箔制作空调换热器导热翅片材就是其中的一个代表。空调正逐步向小型化、高效能、高寿命方向发展。而空调换热片也相应向超薄及高强度方向发展。20世纪80年代换热片厚度为0.15—0.2ram,而现今的厚度仅在0.09到0.15mm之间。但是如何处理铝箔韧性、强度、伸长率间的关系成为需要解决的问题。
发明内容
本发明的目的是提供一种高性能铝合金空调箔,通过对铝合金材质成分进行改进,并且优化处理方法,提升空调箔的性能。
本发明通过以下技术方案实现:
一种高性能铝合金空调箔,包括以下重量比的成分:Si0.32%、Fe0.47%、0.005%<Cu<0.02%、Mn0.52%、Zn0.18%、Ti0.05%、In0.045%、Be0.002%、余量为Al和不可避免的杂质;所述铝合金空调箔经过熔炼、铸轧、轧制、箔材轧制制得。
所述成分Mn的78%加入是在熔炼步骤中加入,剩余的22%是在铸轧步骤中加入,Ti加入是在铸轧步骤中加入。通过将各成分分开加入,使晶粒细化,提升铝合金空调箔的强度和韧性。
所述铸轧步骤将板材轧至厚度为6.5mm。
所述轧制步骤,将铸轧后的板材经过8道次轧至0.4mm,各步分别轧制到6mm、4.2mm、2.8mm、2mm、1.25mm、0.8mm、0.45mm、0.25mm。所述箔材轧制使用3道次轧制,各步分别轧制到0.18mm、0.12mm、0.08mm。使用8道次轧制,3次箔材轧制大大提升了轧制的效果,可以保持铝合金的结构,保持空调箔的力学性能,相对于常规轧制方式,可以更好的保持空调箔的性能。
本发明的有益效果:本发明的高性能铝合金空调箔通过对其成分及各成分加入方法进行优化改进,大大提升了空调箔的综合性能,其抗拉强度达到131MPa,延伸率为28-30%,杯凸值≥7.1,使空调箔适用于多种空调。
