About 7xxx aluminum alloys
7xxx aluminum alloys are alloyed with zinc and reach the highest strengths in the wrought family. Weldability is poor and corrosion resistance trails 5xxx and 6xxx. 7075 is the aerospace standard for highly loaded structure; 7050 trades a small amount of strength for better fracture toughness.
