My prime gig is
ewaste but i've been experimenting with copper and aluminum over the winter. Most of the wire i run into is 16 gauge stranded or smaller.
On the upside:
1:Recovery seems to be fairly good. It seems to be running at a ratio of about 70% copper to 30% insulation by weight.
2: You seem to get about 3x the return when you sell bare wire vs. unstripped.
On the downside:
1: It's time consuming to strip. I spent a day casually stripping in my spare time recently.It was just something to keep my hands busy & pass the time when i wasn't doing something else. It might have been a couple of hours in total. Net result : 8/10ths of a pound at the end of the day when i weighed it up.
2: It's stranded. It's more difficult to strip than heavier gauge single strand wire.
3: It's running at about 50/50 with about 1/2 being bare copper and about 1/2 being tinned wire -or- maybe even something else. The tinned stuff is a bit of a question. It ought to show some kind of green color in the flame when it's heated with a torch if it's got some copper content. It's not showing green so it might be an alloy of aluminum and magnesium ?
4: Strictly speaking ... A stripped wire really ought to be classed as bare bright but your yard might downgrade it to #2 copper because the strands are smaller than a pencil lead. ( 14 GA.)
All around : It seems like the disadvantages of stripping outweigh the advantages. It would be a lot quicker and easier just to sell it as insulated wire and get what you can for it at the yard.
