6000 series is alloyed primarily with Magnesium and Silicon. Usual range of strengths are in the range of 300MPa yield. 7000 series is primarily alloyed with Zinc, Magnesium, Silicon and Copper. Usual range of strengths are 480-550MPa yield.

6000 is tougher, and far easier to weld. However both need proper heat-treatment after welding to restore strength to the weld zone.
