Research on corrosion resistance of aluminum strip produced by casting and rolling billets
In order to investigate the corrosion resistance of 1 ××× and 3 ××× series alu-minum alloy casting and rolling billets after cold rolling,the corrosion resistance of five kinds of aluminum alloys in H24 temper were tested with exfoliation corrosion test,and SEM,EDS,and EWS were used to detect and analyze the corrosion morphologies,composition of corrosion products and metal matrix,and the weight before and after corrosion.The results show that the addition of Fe and Cu elements can reduce the corrosion resistance of the test aluminum alloys,while the addition of Mn and Mg can improve the corrosion resistance of the test aluminum alloys.The higher the purity of aluminum alloys,the better their corrosion resistance.
