An unequal diameter twin roll caster was useful for clad strip casting. This paper described features of clad strip casting using this caster and clad strip. The first layer was Al-Si alloy and the second layer was Al-Mn alloy. The clad strip could be cast directly from melt. The two pieces of strip could be connected easily by very small force, for example, 9N/mm width. The clad strip does not peel off at the interface after bending until broken. Two pieces of strip were connected strongly. The clad strip was rapidly solidified like a single strip. The interface was clear and Si of the first layer did not diffuse into the second layer.
