5052 is commonly used in sheet metal applications as it is much easier to bend and flange. Yes, 7075 is harder and has a higher yield strength.... but, good luck shaping it as easily as 5052. In fact, the low radius bends you see on most sheet metal parts in FIRST (148, 228, Kitbot frame) would probably crack 7075 rather than nicely bend it.

I didn't think he was going to bend it, as shown in his CAD drawing. Yes you are right about the 7075 cracking.
