Norcal...
There have been firings in Northern California over this issue. I forget if it was Oakland or Sacramento, but two fellows were canned for pocketing ALL of the scrap value for years from old electrical equipment.
For your amusement, really old electrical gear is unlikely to use any aluminum. Instead you'll find copper, silver and tin.
Aluminum bussing never took off until its price came down -- a lot. That was a post WWII event.
Government procurement, however, was slow to change. So government purchased electrical anything stayed with copper decades after aluminum took over the commercial field.
The cashed out scrap that the above fellows junked was estimated to be in the millions. ( They sat at the top of the system. Now that the Feds are insisting on 1099s for scrap merchants some boys are in for a shock.)

Talk to a re-winding shop. If they can't do it they'll know who can.
