For my money, if I used AL, I'd check the "certs" and see if the
fittings were made from 6061 T0, (high Copper, no tempering) vs. a
more brittle 5XXX or 7XXX series Aluminum, T2-T6.
-For example, the 6XXX series is used for vibration resitance and
extreme radius forming: 6061 sheet-metal can be bent in a press to
a 180-degree radius, essentially making a "folded sheet", which in the
case I cite, was cheaper than having the mill do it for us.
-6061 in billet stock run off a screw machine for fittings would be
the way to go.

I'm wondering if there might not be problem with aluminum fracturing
due to work hardening from road vibrations?
