I bet that is tinned copper, not aluminum.

Yes, it does have the UL sticker. One note of info, both wires in the
fixture are aluminum not copper, but the ground wire is copper.
Thanks again,
If the fixture gives off a lot of heat, the wires are probably nickel,
definitely not aluminum

Means what it says. The newer cheaper fixtures run hotter and require wire
with the better rated insulation.
It really is a potential hazard to use this fixture with older wires. It
can bake the insulation to a brittle state.

How's that? Electrons dissipated in the incandescent filament know
they're in a "newer cheaper fixture" somehow and thus generate more
heat? Does not compute...

They are of piss poor design and enclosed mostly where the older ones were
not. The watt to btu conversion has always been the same.
