Do they make a WIRE NUT for al to al ????????????????????????????????????????????????????????????????????????????????????????????
 
I have not found a wirenut rated for AL to AL.

From the attached, it appears WAGOs may be if their compound is used,

null

Connecting aluminum and copper conductors is relatively rare in building installations. But if it's necessary, use WAGO Alu-Plus Contact Paste to connect aluminum and copper conductors with WAGO Connectors – quickly, easily and reliably.

Why would the purple nuts that you use for alum to copper pig tail, not work for alum to alum.
When you splice in a box you usually have two alum and your pig-tailing to the recep

From the Ideal website:

For use only on copper-to-copper or aluminum-to-copper connections. Do not use on aluminum-to-aluminum connections.

Then how in the heck do you splice into a receptacle box?
Most recep your going to have an in and out so that two aluminum with a 1 copper pigtail

I recently asked if adding a capped copper pigtail to an AL-to-AL splice would work.

I think the answer is that we have to look at the approved conductor combinations.
 
There are several ways to use a pigtail with two ALs.
Nobody says you have to connect the pigtail to anything.

1 #10 Al solid w/ 1 or 2 #10 Cu solid
1 #10 Al w/ 1 or 2 #12 Cu
2 #10 Al solid w/ 1 #12 Cu
1 #10 Al w/ 1 or 2 #14 Cu
2 #10 Al solid w/ 1 #14 Cu
2 #12 Al solid w/ 1 #10 Cu
1 #12 Al solid w/ 1 or 2 #10 Cu
1 #12 Al stranded w/ 1 or 2 #10 Cu solid
1 #12 Al w/ 1 or 2 #12 Cu
2 #12 Al solid w/ 1 #12 Cu
1 #12 Al w/ 1 or 2 #14 Cu
2 #12 Al solid w/ 1 #14 Cu
1 #10 Al w/ 1 or 2 #18 Cu
2 #10 Al solid w/ 1 #18 Cu
1 #12 Al w/ 1 or 2 #16 Cu
2 #12 Al solid w/ 1 #16 Cu
1 #10 Al w/ 1 or 2 #16 Cu
2 #10 Al solid w/ 1 #16 Cu
1 #12 Al w/ 1 or 2 #18 Cu
2 #12 Al Solid w/ 1 #18 Cu

Reading the instructions it's not just any WAGO but limited to use with the 222, 2273, and 224 lighting connector for splicing that might fit into standard device box (switch/receptical). They do give warning that not for use with the 221 series. (my favorite for sizing)
 
Alumiconn connectors are the only ones that I know of. Here in Florida it's big business. People are buying homes wired with aluminum and insurance companies won't insure them unless the devices are terminated with copper pigtails. Nothing like spending another $5K when you're buying an overpriced home to begin with.

Now see my problem is I have never seen one that does not have only 3 inches of conductors in the back of box and that wire is so brittle you basically have one chance to thread the nut on or you comprise the conductor and it’s snaps.

I understand it can be difficult. In the 2023 NEC, they even have a revision in box fill that requires you to count the Alumiconns as volume allowances.
