Clad strip casting was tried using a single roll caster and two types of twin roll casters. The clad strip could be cast directly from melt. The two pieces of strips could be connected easily by very small force, for example, 5N/mm width. Interface between the strips was formed clearly, and two pieces of strips was connected strongly. To cast strongly connected clad strip, connecting surface had to be semi-solid condition. Both of overlay type clad strip and inlay type clad strip could be cast using the twin roll caster in this study. The clad strip was rapidly solidified like a single strip. Size of copper roll was φ250×100 mm. Roll speed was 20 m/min. Al-12%Si and A1050 were used. Width of the strip was 20〜50 mm. Thickness of the clad strip was 1.5〜3mm.
