Couldn't find a lot of info on how much copper was in the various ACR's. I used the utility knife method a couple of months ago on a double stacked unit and got 58% cu the rest was aluminum and dirt. A buddy pointed out the different amount of stacks would have varying cu contents. So to show how smart I wuz, I tossed out a high recovery rate.
I gathered up a good sample of a couple of each (800lbs) and shredded them.
My result 47% cu I don't like guessing.

Does anyone have any info on cu content on individual 1,2,3 or 4 stack coils. I think my double stack number is wrong
