Question:

What is the difference between #1 and #2 copper?

Have 2 inch thick wire. Stripped it down and got about 30 wires, different gauges. Is that #1 and was it worth doing.

Answer:

No.1 Heavy Scrap Copper Shall consist of clean unalloyed copper solids and must be uncoated. May include copper clippings, punchings, bus bars, commutator segments clean copper pipe or tubing and Copper wire over 1/16 thick but free of burnt or brittle wire. This grade is equivalent to the ISRI code CANDY No 1 copper goes for about: $1.12 / lb . No.2 Copper Wire shall consist of clean unalloyed copper wire, free of hair wire, brittle burnt wire and excessive oils minimum copper content of 94% remelt recovery rate. Equivalent to ISRI code Birch No 2 copper goes for about: $1.97 / lb . So to make #1 Copper into #2, its worth $0.85 a pound, so it depends on how long it took you, and how much material you had when finished.
