METHOD FOR FORMING PROCESSING OF 6000 SERIES ALUMINUM ALLOY MATERIAL, AND FORMING PROCESSED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for forming processing of a 6000 series aluminum alloy material, which can form a more complex shaped molding product, and after artificial aging, obtain a high strengthened molding product having a proof strength of 250 MPa or more.SOLUTION: There is provided the method for forming processing of a 6000 series aluminum alloy material that includes, by mass%, 0.3-4.0% Si, 0.3-2.0% Mg, 2.0% or less Cu, 1.5% or less Mn, 1.5% or less Fe, 2.0% or less Zn, 0.50% or less Cr, 0.50% or less Zr, 0.50% or less Ti, 0.50% or less V, and the balance aluminum with inevitable impurities. The method includes the steps of: performing a solution treatment of the aluminum alloy material; forming processing the material in a die after the solution treatment; and performing a quenching treatment of the material following the forming processing by cooling the material in the die to a temperature of 250°C or less.
