What difference does "aircraft grade" aluminum make over a ordinary industrial aluminum?

I picked up an original "Razor Scooter" kick scooter from Wal-Mart and the box says it's made of "aircraft grade aluminum" in China. Whatever that means.

What makes aluminum an "aircraft grade" and beside the buzzwords, what difference does it make over ordinary industrial aluminum alloy?

Does it simply mean it happens to be the same alloy used on aircraft and other aluminum chase?
 
It means your scooter can fly to Russian if they simply melt it down along with 10,000 other scooters, shape it, add an engine/ rocket fuel/ a pilot, and a will to soar with the birds.

"7xxx series ? Zinc in amounts of 1 to 8% is the major alloying element in this group, and when coupled with magnesium and copper (or without copper) results in heat-treatable alloys of very high strength. Usually other elements such as manganese and chromium are also added in small quantities. The out-standing member of this group is 7075, 7050 and 7049, which is among the highest strength alloys available and is used in air-frame structures and for highly stressed parts. "
