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

Aluminium comes in various grades, most aluminium objects are made from a 6000 series alloy like 6061 or 6082, they’re soft and cheap with few additives, but there’s 7000 or 2000 series alloys like 7075, 7074 or 2024 that are much stronger because they have alot more alloying elements in them, like copper which makes them more expensive.
They may be using a high strength alloy or maybe a low strength alloy certified to a higher standard but “space grade” is mostly nonsense
If it lists the alloy in the 6000 range it’s just aluminium, if it’s in the 2000 or 7000 range it’s the good stuff
