I always have problems with any item that uses Bull dust descriptions to fool people.
"Aircraft grade aluminium " is one such term that is totally meaningless.
There is no Aircraft grade anything except fuel.
Aluminium used in the aircraft industry is simpily primary grade material that any one can buy at any aluminium supply.
Primary = no scrap used in it's production, all virgin metal.
The really strong stuff as used in space missions is double vacuum melted but that costs in the hundreds per kg
