Purpose: of this paper is to clear the possibility of high speed roll casting of thin strips of two aluminum alloys: 6061 and recycled 6061. Mechanical properties of the roll cast 6061 and recycled 6061 strips were investigated in the frame of this purpose. Design/methodology/approach: Methods used in the present study were high speed twin roll caster and low temperature casting. These methods were used to realize rapid solidification and increase the casting speed. Findings: are that 6061 and recycled 6061 could be cast at speed of 60 m/min. Casted strips were about 3 mm thick. As cast strip could be cold-rolled down to sheet of 1 mm thick. 180 degrees bending test was operated on the sheet after T4 heat treatment and crack was not worse than 6022 which is typical aluminum alloy for sheet of the automobile. This result means the roll cast 6061 can be used as a sheet for body of the automobile instead of 6022. Research limitations/implications: Research limitation is that the width of the strip was 100 mm and investigation of the properties were enough for practical use. Wider strip must be cast using the twin roll caster of the size for production. Originality/value: The economy sheet of the 6061 for the auto mobile can be produced by the high speed twin roll caster. 6061 is typical wrought aluminum alloy of 6000 series. Therefore, the sheet of 6061 will become economy. 6061 can be recycled at two times when the 6061 is cast into strip by the high speed roll casting.
