Hi
The other is that is oxidizes quickly when exposed to air.
Getting loose and oxidizing make for a hot connection when
current of any kind goes through it. Add some flammable
material and you have a nice bond fire.
What were they thinking?

I shudder when I picture aluminum core wiring...
I just have visions
of it evaporating under load! :-)
I am not sure how old youor house is, but beware - lots in the town have
(or had) Al. Mine did (rather, I am still yanking it out).
One of the big problems with Aluminum is that it flows under pressure -
the pressure of a screw, for example. Tighten down a screw on a fixture,
and next year, you will probably be able to tighten a little more. Then
next year, a little more.
