Why would the aluminum stock not be useful after 10 years, oxidation?

Aluminum is very oxidation resistant once the initial thin oxide layer forms. I doubt that is the issue.

I would guess the reason is similar and would be weathering/erosion due to being outside and pelted with sand/rain/etc.

So the 'Buying spree' graph is apparently showing a surge of import. But it really doesn't show anything like that. Or am I just misunderstanding something?

It might be in specific forms ready to be processed - eg. blocks of specific dimensions or weights.

After 10 years outside, it's probably covered in dust and grime, and gotten an oxide layer. It probably isn't immediately sellable to a car factory...

But it could be reprocessed very inexpensively and become sellable. The loss of value would probably be well under 1%.

People saying "it's so old, it's basically scrap" either don't know what they're talking about, or they're deliberately deceiving - and being market traders, I suspect the latter in the hopes of pushing market prices higher.
