<p><P>PROBLEM TO BE SOLVED: To provide an Al-Mg-Si based aluminum alloy which has excellent strength and ductility, and in which the coarsening of recrystallized grains can be suppressed. <P>SOLUTION: This invention is characterized in that 0.05 to 0.24 wt.% Zn and 0.05 to 0.25 wt.% Ni are added to an Al-Mg-Si based aluminum alloy. Further, by adding 0.05 to 0.25 wt.% V thereto, its strength is more improved, and further, the effect of suppressing the coarsening of recrystallized grains harmful for the toughness, corrosion resistance or the like in the final product can be increased. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
