Strong and safe enough?

And seriously what does aerospace quality aluminum really even mean anymore, tell us the grade if its so special.

It actually means nothing about it's strength, it never did. It's just used as a marketing term because it sounds trick. Some aerospace applications require a strong, fatigue-resistant aluminum, some don't. Which one are you getting? What were their metrics when choosing a material? Something to ask them, anyway.
