I made a run to the yard today to get some of the lower grade stuff out of the shop. The aluminum and #2 insulated were starting to pile up. Threw in a little bit of copper just to sweeten the payout.
The service at the yard is really good but i've got a question on the grading at the small scale. The scale guy classed my extruded as sheet so that error was pretty clear cut. I did have some question on what constitutes light copper grade.
I had some copper sheet in the mix. Some was unused but had oxidation. Some was a copper kettle which i had cut all of the ferrous out of. Some motor windings. A solid copper heat exchanger that had paint on it. I would have figured it for being #2 but that bucket full was downgraded to light copper. Seems like kind of an ignorant thing to do but i've sold at this yard before and would like to keep doing business with them.
The problem could be on my end. Could you provide some guidance on the line between #2 and #3 grades light copper ?
I always figured light copper grade as being tearoffs from old copper roofs. You know ... all green with tar on it ?
