Is it just marketing or is there an actual structural difference?

I can’t answer specific to aluminum, but I know that for things going into space, we have to putin them into chambers where the temperature is brought up and down over a long period of time, long test times doing this, logging, ensuring it still functions. I imagine that space grade aluminum would simply mean it is tested in a similar manner, won’t warp or degrade in space.
Saying that, I have no idea if they even use aluminum in space.
