So real close look tells me its Copper wire with a Tin coating. As I was cutting thru the wire, it was smearing the softer tin across the copper wires cut face.
Thats why it looked Silver all the way thru.

I have found this happens a lot when I do this. For instance I cut thru the Silver coloured backing plate on a flat transistor & it looked Silver all the way thru.
But when I scraped it across a knife sharpening stone, the Copper colour came back out.

Yeah yeah, yah just smearing the Tin coating over the face of the Copper wire.



Its Copper wire.

I'm really pretty sure it's not copper. However, I took a load in today and the scrap guy just threw it on the scale with my copper so i got copper price for it!
