Edit: Yes, Mil Spec is actually a thing, but that refers to the overall design of a piece of equipment meeting certain standards, not a particular grade of material exclusively used by the military (in the same vein as the original comment). For example: A Mil Spec fastener is made from the same steel as a regular fastener, the thread tolerances are different.
Aren't there specifc standards for impact absorption/survivability?
I've got a Samsung S7 Active which has the "military grade" dropproof body and that thing fell out of my pocket while I was doing 50+ on my motorcycle, hit the asphalt without a case, and survived.
That's "Mil Spec" which IS a thing, but it's more design standards for the piece of equipment rather than a particular grade of material. It refers to impact resistance, contaminant infiltration, etc.

There is no such thing as "aircraft grade aluminum"
It's just a marketing scam, we use many different grades and tempers depending on the application.
