Outline of Final Research Achievements

A scraper was proposed to make clad strip from molten metals without the mixture of molten metals. The AC4C is typical aluminum alloy for casting. The two layers clad strip consisting from A3003 and AC4C had thickness ratio one to five. Full contacting bending could be conducted of the two layers clad strip which outer strip was the A3003 without cracks. Deep drawing test was conducted and 1.8 of Limiting Drawing Ratio (LDR) was attained. Three layers, which base strip was cast from the aluminum alloy for casting and overlay strips were cast from the wrought aluminum alloy, could be cast by a vertical type tandem twin roll caster. Continuous bending test was conducted to investigate the bonding condition. The 180 degree full bending could be conducted on the three layers clad strip without occurring of the crack at the outer surface.
