holes in the said aluminum ,what would do it the fastest? other than mercury

Sodium hydroxide (lye) or hydrochloric acid (muriatic acid) each attack
aluminum with vigor.

And note that both produce explosive hydrogen in copious quantities... be
careful!!

I have to ask what is "180 degree thin aluminum"? I've never heard of this
description.

thin aluminum at 180 degrees farenheit, sorry

In that case, you don't want to use muriatic acid (HCl). The fumes
given off by the acid vaporizing on the hot aluminum would be REALLY
REALLY terrible. I've heated it to 150F and it's not something that
I'll do again.

Agreed, unless one has a fume hood. I often used my acids at almost
boiling temps, where they did their work the fastest.

Ferric chloride will eat aluminum up pretty handily. I found this out as a
kid when I didn't have a plastic container for etching a PCB, so instead I
used an aluminum tray. Oops.
