This is an interesting discussion - if a little old. When I looked up the properties, 7075 seemed to be much stronger (tensile strength), but very little stiffer (elastic modulus still around 70GPa) so I didn't see much point in using it - or have I been fed duff data????

Yeah, that sounds right... I bought a few sheets of 7075T6 a while back to make a few bottle openers from - bottle-tops would chew up anything made from 6082. The 7075 still looks perfectly fine years later. Not done a side by side bend test, but there's probably not much between them.
Some useful info:

Thanks for the link..... though I notice there doesn't seem to be any hardness data, which maybe makes all the difference on your beer enabling products :-) I had a bracket out of a Bentley that was made of some such alloy and man was it stiff - quite unlike any ali I've ever touched before.

Around 90 Brinell for 6082T6 vs 150 Brinell for 7075T6.
