摘要：This invention relates to a 6000-series aluminum extruded material containingmagnesium (0.3% to 0.7% by mass), silicon (0.7% to 1.5% by mass), copper (0.35% or lessby mass), iron (0.35% or less by mass), titanium (0.005% to 0.1% by mass), manganese(0.05% to 0.30% by mass), chrome (0.10% or less by mass), and zirconium (0.10% or lessby mass) (provided that at least one transition element selected from the groupconsisting of manganese, chromium, and zirconium is contained in a total amountrepresenting 0.05% to 0.40% by mass), with the balance comprising aluminum withinevitable impurities, such aluminium extruded material having a predetermined yieldstrength of 180 MPa or more with an increase of 60 MPa as a result of a thermal historycorresponding to paint baking. Such 6000-series aluminium extruded profile is superior inpaint-baking hardenability and thus the yield strength thereof can be secured to a levelapplicable to structural members of automobiles and the like with the use of a thermalhistory corresponding to paint baking.
