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

When something is marketed as being made with space-grade aluminum, that just means that it’s the same aluminum alloy used in spacecraft. It’s really just a marketing strategy, as space-grade aluminum isn’t really all that special, but it does sound higher quality.
Similarly, surgical grade steel is the same kind of steel used in scalpels and other medical instruments. Those scalpels lose their edge fast, and they’re disposed of after surgery. So really, surgical grade means cheap, but sounds high quality.
Military grade is a similar thing. It means a product is made from materials used in general issue military equipment. It doesn’t mean “indestructible” by any stretch.
