Abstract
A method for producing an extruded material includes: casting a billet at a casting speed of 60 mm/min or more using an alloy containing: 0.50 to 1.0% of Mg, 0.80 to 1.30% of Si, 0.10 to 0.60% of Mn, 0.05 to 0.35% of Fe, 0.35% by mass or less of Cu, less than 0.10% by mass of Cr, Zr, Zn respectively, 0.10% by mass or less of Ti, and the balance being aluminum, the alloy having 0.85 to 1.75% of stoichiometric MgS with 0.10 to 0.85% of excess Si, and 0.15 to 0.95% of Mn and Fe; homogenizing at 560 to 590° C. for 2 to 8 hours, cooling at 50° C./h or more; preheating at 400 to 550° C., extruding the billet into the extruded material, cooling the extruded material from 460 to 550° C. at an average rate of 350° C./min or more; and applying artificial aging.
