Again:
To put it politely:
You have no idea what you're talking about at all.

In short:
the op does not seem to be informed on the subject he's discussing
As an engineer I have to say that this is the least informed technical statement I have ever heard.
Just an FYI that little 2mm section can resist around 110 lbs of force, and when bending there is also the lower section, the back and the other side to consider.
This is an incredibly silly and technically useless way of stating things which varries a lot based on temperature and how much you shake the bottle. It also depends on the coke bottle size.
Just to do the simple conversion we're talking of around 8.5 tons of force here for a fully shaken, hot, 2 liter bottle at the high end and zero at the low end for a cold unshaken bottle of any size.
Seriously you have no idea what you're talking about. The paint adhesion and molecular bonding of the anodizing has NOTHING to do with the material being soft. Also, did you not read my other post? Your phone would literally fall apart if made from less tempered alloy as it would crack at the corners and not bend like it's supposed to. It's made the way it's made for a reason.
Seriously just stop. You don't know what you are talking about. If they made the phone out of the materials you propose it would literally fall apart in your hand. You do not understand materials science at all.
There have been a handfull of bent iPhone 5's out of millions, this is more likely due to defects in the material than the design.
In fact the photos of the bent iPhone looks very much like what would happen if the phone was made out of the materials you proposed.
