Alu ages differently than steel...both have issues, just differences
Serious off roaders, or those who know via hard knock schooling, only run steel
wheels...or knowing the weakness of alu in that application, don't go fast out there
Why I'll not take my plastic bicycle (+$7K carbon fiber) on the train. Have taken
my alu bicycle, but prefer taking my steel Coastie on the train with no worries
Many get mixed up with the marketing (factual) claims that Carbon Fiber, etc
has higher strength than steel...on that application and usually in tension only
Understand and accept alu for a 'truck' body (passenger portion), but I'll not
touch the working 'bed' to alu...sure make it thick enough, but then it will
weigh much more and then why?...as that then defeat the whole purpose of going
alu to lighten it
Alu body work requires a much higher level of know-how. Back to off roader not
wanting alu wheels. I've pounded a steel wheel bent hitting boulders and know
that an alu wheel would have cracked hitting it, or crack pounding it back.
Alu work hardens much quicker than steel. Even dead soft alu and worse any that
has been hardened to T6
Since it requires a higher paid body shop person, and higher levels of 'stuff'
(mainly welding) and often toss and replace with new...will cost more to fix
than steel sheetmetal
Plastic bodied truck (carbon fiber) will be even more expensive and more totaled
trucks/SUVs. Not crumple zone designed, as plastic explodes doing 'crumple zone'
duties...but a person who can afford an Aventador should be able to afford the
repair cost or a new one...approx $400,000.00
