Yes, and with a name like "crashtech" who are we to argue.
One of the things body shops often need to do to repair a vehicle is basically to stretch the vehicle so that all four wheels are where they need to be. It's more involved that that, of course, but the fact is Al does not handle flexing very well. A steel piece may be bent then rebent to the original shape and the steel may not suffer much loss in strength. Al, on the other hand, will far more likely break when being bent back. Forming or reforming Al is far more complicated than steel.

Not sure where you got that idea about Al vs Steel, but it all depends on the alloy and temper. A lot of Al alloys and tempers are very easy to form, I've seen many complex curves formed by aircraft mechanics in 0.100 Al plate, and thicker formed by machine.
The other option to save weight would be high strength steel, which tend to be very brittle, so forming and especially reforming become much more complicated or impossible.
The 6061-T6 used by Ford is very common in aircraft hydraulic lines due to how easy it is to bend. Hydraulic lines are pretty much the only area I see 6061-T6 used on large aircraft, since other alloys are stronger but have other drawbacks.
