A single-roll caster and two kinds of twin-roll casters to cast clad strips were designed and assembled. One of twin-roll casters was suitable for clad strip casting. This twin-roll caster can cast clad strips of aluminum alloys at the speed of 20m/min. The thickness of the clad strip is about 2.0mm. The clad strip has a clear interface between the two strips. The clad strip is connected strongly at the interface. Therefore, the clad strip does not peel off at the interface after bending until broken. The clad ratio of the thickness between the overlay strip and the base strip is 2:1-1:10. An alloy with a melting point lower than that of the base strip is suitable for the overlay strip. The roll speed, cooling distance of the base strip, and the temperatures of the melt for the overlay strip are important factors in producing sound clad strips.
