Yes it is.

Answer 3

Copper oxidises (tarnishes) and goes green eventually in the presence of air an moisture. You need to get this off to make it chemically clean for soldering and the like (bright and shiny like a new penny or cent) - use emery paper or steel wool.

If youare talking scrap metal - it means no insulant on it and not blackened.
