Interesting. Pretty much what what I learned about aluminum over the years.
Add to think of the old days with steel beer/soda cans...couldn't
crush them as easily as you can with today's ALU cans...
Wasn't going to comment on this, again, but it is pure science here
This is about tensile strength...anyone ever take a college materials
class? Or Strength of Materials class? Tensile Strength is its elongation
strength, generally speaking
Meaning stretch, as in being hit with those building block...that dented
it...that stretched it beyond it's plasticity point (ability to return
to original shape) and into yield (won't return) and beyond to crack
Here are some basic number off the top of my head from college days
decades ago...and confirmed by looking them up for specific numbers... :B
Wikipeda, Ultimate tensile strength
Of course if weight is of primary, then ALU. If strength is the primary,
then steel.
This should give an idea of the differences between aluminum and steel
Aluminum
6061-T6 is what am guessing the family of which the Ford bed is made from
Has an Ultimate Tensile Strength number of 300 MPa. There are higher, but
exotic ($$$$) and that is what I'd consider 'military grade'...
I've designed stuff for the military and even black badge...6061-T6 is
used, but the 'good' stuff that is real military grade is way stronger
and much, much, much more expensive that 6061-T6
Steel
Mud hen (mild) 1090 is 841 MPa and they also have higher alloys and again
exotic ($$$$$$$)
Also, don't know where you folks buy your building materials from, but
in my area...they ALL dump them into the bed just like that video
Or some times if you buy it by the pallet, they load it with a fork
lift. Pallet with wire cage to hold cobble stones/etc in and are
pre-weighed
