It is very hard to work with to make bumpers. It has a generous minimum bend radius or it will break. If you look at the top bend across the front of the bumper, that is the dead giveaway that it isn't and can't be 6061 T6. It is a tight 90 done with conventional tooling on a press brake used for steel.
It is never good to assume.
You aren't paying attention. Look at the bends, you can not do that with 6061 T6.
This one says it's 6061-T6 and it appears to have the same bend though Blaine:

Unless I'm missing not seeing something.
I'm not doubting you at all. I just find it weird that those appear to be the same bumpers, one just has the bull-bar / winch guard, while the other does not.
