The pigtails on these are aluminum. I found that out when cutting mine short. Of course, I cannot verify that other brands do the same thing for their pigtails.

Good to know you can get the long wire that is copper.

Note in that link they have the electrical data for the mono version, so ignore that. They have the poly version (I now have two of them)

Is it possible that the wire is tinned copper? Some of the pre-made solar cables that I've purchased have tinned copper and it can look like aluminum if you don't look at the cut end.

EDIT--I worked away at it some more and in better light it does appear to be copper under the tin. Good to learn that, thanks.

I have a piece of it so I was able to check just now. Scraped the strands with a knife and they just got shinier.

The cable info says:

(UL)E310273 RHH OR RHW-2 / E305787 PV WIRE 12AWG 90C WET OR DRY 600V
SUN RES -40C >> H + S 12583780-769871 RADOX SMART << TUV.COM ID:
0811307400 PV1-F 4MM2 120C 0.6/1 KV

Whatever that all means! :)
