Yes, normal taps work fine in Aluminum. Check to make sure you

I try not to machine when in a hurry or frustrated. Instead of making it
work, I just unshipped the collet, put away the clamps and cleaned up my
mill.

I see that Windex is supposed to be a good tapping fluid for aluminum...
Was looking on the web to see who handles Tapmagic in southern
Wisconsin... When Beloit Machine Supply closed, there's not much
machinist stuff around local...

WD-40 works and is available almost everywhere.

WD40, The Wonder Drug. g

If you're going to use Tap Magic, make sure it's Tap Magic Aluminum. The
older Tap Magic for steel (and maybe the newer stuff -- mine is old) will
turn aluminum black, boil and bubble, and eat the threads away. Otherwise,
it's just fine. d8-)

Kerosene is the traditional tapping fluid for aluminum. But WD40 probably
won't hurt.
