Corrosion of EN-AW 3105 Aluminum Strip Produced via Twin-Roll Casting with a Steel/Copper Roll Pair

Utilizing copper rollsCopper roll in twin-roll casting (TRC)Twin-roll casting due to high process productivitiesProductivity provided by high thermal conductivity of copperCopper when used as a shell material is a well-known application to fulfill the increasing material demand seasonally and EN-AW 3105 is one of those aluminum alloysAluminum alloys, which is produced by using a steel/copper rollCopper roll pair. However, as-cast material microstructureMicrostructure after solidificationSolidification is distinctive on the material surfaceSurface which is in contact with the copper rollCopper roll when compared to the other surfaceSurface in contact with the steel roll. These microstructural discrepancies observed at as-cast thickness are inherited in the final product after rolling and annealing processes to a certain extent. In this study, corrosionCorrosion properties of an EN-AW 3105 aluminumAluminum strip produced via TRC were scrutinized and it was concluded that the material surfaceSurface, which solidified in contact with the copper rollCopper roll performed better corrosionCorrosion properties with respect to other surfaceSurface.
