Sounds funny. The flux is "compliant", but they suggest that you use it
with tin/lead solder.

Subject: Re: Soldering to Aluminum?
Pete,
Seems to me there was recent thread here on something similar. We have
soldered to stainless steel and I think the process is similar for
aluminum. It has to do with the flux used. Word of caution... I
believe it is an acid based flux so how it is applied and washed off may
be of concern.
From McMaster-Carr website:
Aluminum Soldering Flux
Use this paste flux with aluminum solder and any tin/lead solder to
solder aluminum and aluminum alloys. Also for use with copper, chrome,
and brass. Meets DOD 1866 and is ROHS compliant.

I have not tried it.

Subject: [TN] Soldering to Aluminum?
Has anyone tried soldering lead free to an Aluminum circuit on
polyester?
We are looking at a very simple one component circuit that needs to be
on a material with some flexibility. We do run millions of feet of
aluminum on polyester passive circuits in one of our plants. I am being
asked to see if we can take advantage of the in house production to save
some cost.
My other thought is to just try a conductive adhesive, but we might need
to do some tooling for that, as this would require about 3 million of
these circuits/year.
