RESIN-COATED ALUMINUM ALLOY SHEET FOR DRAWN AND IRONED CANS

WIPO Patent Application WO/1998/049360

A1

A resin-coated aluminum alloy sheet which makes it possible to form drawn and ironed cans having strengths necessary for suppressing the breakage of the walls when complicated machining inclusive of bending and unbending at a die shoulder radius portion having a small shoulder radius and subsequent ironing are carried out as a dry process, and which can provide an aluminum alloy film having a sufficient adhesive strength after the machining. The sheet is manufactured by applying a silane treatment using a silane coupling agent alone or a composite treatment using both chromium phosphate and a silane coupling agent to an aluminum alloy sheet whose contents of Mn, Mg, Si, Cu, Fe and (Si+Fe), thickness and yield strength are controlled to be in predetermined ranges and then coating the sheet with a thermoplastic resin.
