Ripple marks are generated on the lower roll surface of the Al-Mg alloy strip produced by the twin roll method, and porosity is generated in the final solidified part. At the solidification distance of 100 mm, many ripple marks occurred at the roll speed of 20 m/min and roll load of 16 N/mm. By cladding with an alloy other than the Al-Mg alloy that has a higher solidus temperature than the liquidus line of the Al-Mg alloy in the 2nd layer and the AlMg alloy in the 1st layer, the formation of porosity was suppressed.
