Abstract
In this work, the mechanical properties of roll-cast recycled aluminum alloy were investigated. Fe was added to 6111 aluminum alloy to simulate recycled aluminum alloy. The Fe content was varied between 0.14 and 1.02 mass%. A high-speed twin roll caster was used because it exhibits better cooling characteristics than the conventional twin roll casters. The strip was cast at a speed of 60 m/min and the resulting strip microstructure was not columnar, but equiaxed or globular. When the Fe content was 0.4 mass%, the Fe content does not appear to exert any influence on the tension test results after T6 heat treatment, and after a 180-degree bending test no cracks occurred on the outer surface.
