Title: Material of the Crack wires?
Post by: cddc on December 06, 2016, 07:12:36 AM
The cores of the Crack wires do not look like copper, so are they silver or aluminum?

Great, thank you so much for your quick answer Doc.B.

Just a follow-up: I have never seen copper in silver color. So are the silver-colored Crack wires copper alloy?

The copper is plated.

I carefully examined a fresh cut, and did see some copper color from the cross-section.

Boy, it's really hard to see the true color of copper with the silver-colored plating.

Thank you very much, Doc.B!
