Abstract

PURPOSE:To produce an Al alloy rolled plate having excellent formability as well as excellent corrosion resistance and weldability by casting the Al alloy contg. specific ratios of Si, Mg and Fe, rolling it and thereafter subjecting said alloy to a solution heat treatment and quenching treatment. CONSTITUTION:The semicontinuous casting or continuous casting is executed to the molten metal of the alloy having the compsn. formed with, >1.2-1.8% Si, >0.6-1.1% Mg, 0.05-0.5% Fe and the balance consisting substantially of inevitable impurities (in which <0.1% Cu is regulated) with Al. The obtd ingot is rolled and said rolled plate is subjected to the solution heat treatment at 450-590 deg.C. The plate is then quenched at >=5 deg.C/sec cooling ratio. Said Al alloy rolled plate has excellent bulging characteristics and bendability and has excellent formability in such a manner that the generation of a Luders mark does not occur. The strength increases particularly at the paint baking stage after forming. Said plate furthermore has excellent corrosion resistance after painting and has TIG, MIG weldability.
