7075 Aluminum

[jtpackard]

Just a short comment regarding the use of 7075 alum. Yes it is rigid and the
strongest aluminum available, but be aware, its' corrosion resistance is
low. I am using it in a few areas on my SR but also epoxy prime every part.

I've bought a lot to 7075 from Boeing Surplus over the years and it is a
hard alloy and difficult to bend. Most of what I have seen is extruded hat
section and very rigid material.
