Frog Hippity Hoppity Get Off My Property Vintage Shirt
For a toy or random domestic widget to be made out of aluminium that isn't used on aircraft, it'd have to pick a more obscure, more expensive grade - which no designer is going to do unless they specifically need some property of that grade.So yeah, someone designing something out of aluminium that doesn't matter what grade it is is probably going to pick a grade that happens to be used on aircraft too. Then the marketing people turn up and stick "aircraft grade!" in front of it.
